Slamming: how to undo a provider switch you never authorized

Slamming: how to undo a provider switch you never authorized

One day a welcome letter arrives from a phone company you've never heard of, or a text confirms a number transfer you never requested. Your line still works, but you're no longer with the company you thought you were. That has a name: slamming, switching your phone carrier (or, in states where you can choose one, your electricity or gas supplier) without your consent. It's more common than it looks, regulators take complaints about it, and it can be undone if you act fast.

How do they switch my provider without me noticing?

It almost always starts with a pushy sales call. The typical pattern:

1. They call pretending to be your current provider ("we're calling from your phone company to lower your bill") or an independent service that "compares rates."
2. They ask you to confirm details "to verify the offer": your name, address, and date of birth, and sometimes your account number, your account PIN, or the last four digits of your Social Security number.
3. With those details and a recording of you saying "yes" to vague questions, they submit a switch to another company, which then presents that recording as your supposed consent.

Sometimes there isn't even a call: your details just have to be out there (data breaches, online forms, directories) for a dishonest salesperson to submit the switch and pocket the commission. That's why slamming often goes hand in hand with the "say yes" trick: a recorded "yes" doesn't sign a contract, but they use it as a prop to make it look like you agreed.

On cell phones there's a nastier cousin: port-out fraud or a SIM swap, where someone uses your details to move your number to a phone they control. Your calls and texts, including security codes, then go to them. The NoCall blog explains how SIM swapping works.

How do I tell if I've been slammed?

The warning signs:

• A welcome letter or email from a company you never signed up with.
• A text about a number transfer or a new account that you don't recognize. Don't ignore it: it's proof that something is in motion.
• Your provider stops billing you, or you get a final bill with an "early termination" fee.
• A new company name or unfamiliar charges on your bill. For phone service, check your phone bill; for electricity and gas, your next utility bill.
• Changes to your online account, or you suddenly can't log in with your usual password.
• Your cell phone suddenly has no service for no clear reason. If your number was ported out, it's now working on someone else's phone.

Golden rule: any message about a switch you didn't ask for deserves an immediate check. Call your provider (at the official number, one you looked up yourself, never the one in the suspicious message) and ask whether anything is pending on your line or your utility account.

What do I do to reverse it?

Act in this order, and in writing whenever you can:

1. Contact your original provider and explain that you never authorized the switch. If it's still pending, ask them to stop it; if your cell number was ported out, tell them it's fraud and ask them to get it back right away.
2. Complain to the company that switched you, in writing, and ask for a reference number. Demand that the switch be canceled with no penalty and that everything they charged be refunded. Ask them to send you the authorization they claim you gave, whether it's a recording or a signed form. If they can't show that you clearly agreed, that's your strongest argument.
3. Don't pay penalties for the fraudulent switch. If they threaten to send you to collections or report you to the credit bureaus over a contract you never signed, say so explicitly in your complaint. If a wrong entry shows up anyway, dispute it with each bureau (Equifax, Experian, and TransUnion).
4. If they don't reply or they reject your complaint, escalate: for phone service, file a complaint with the Federal Communications Commission (FCC) at 1-888-CALL-FCC (1-888-225-5322); for electricity or gas, contact your state public utility commission. Your state attorney general's consumer protection office can also help. Keep every document and reference number.
5. If they used your Social Security number or other details to impersonate you, also file a report with your local police department and get a recovery plan at IdentityTheft.gov. A police report strengthens any later complaint.

If the switch came with charges on your bank account, ask your bank about disputing them; the NoCall blog also covers what to do right after a phone scam.

How do I protect myself so it doesn't happen again?

• Don't confirm details to anyone who calls you. Not your name, date of birth, address, account number, PIN, or Social Security number. If they say they're your provider, hang up and call the official number yourself.
• Answer with "Hello?" and don't give one-word "yes" answers to closed questions from strangers, like "Can you hear me?"
• Check your bills every month: phone, internet, electricity, gas, and bank statements. Slamming shows up on the bill before anywhere else.
• Lock down your number. Ask your carrier (Verizon, T-Mobile, AT&T, or whoever you use) about a port-out PIN or a number lock, set a strong PIN on your account, and turn on any account or number-transfer alerts it offers.
• Report the number that called to sign you up: these campaigns target thousands of people, and the number usually piles up reports in the spam numbers directory that warn the next person.

Frequently asked questions

Is slamming the same as a switch I asked for and then regretted? No. If you asked for the switch and changed your mind, you're dealing with the new company's cancellation terms. Slamming is a switch you never asked for: it's not about canceling, it's about challenging a change you never authorized.

They say they have a recording of me agreeing. Am I stuck? Not automatically. Ask for the recording and listen to it carefully: check whether it shows that you knew who was calling, understood what you were agreeing to, and clearly said yes to switching. Many fall apart because the information was misleading or the "yes" answered a different question. If it doesn't hold up, say so in your complaint.

Can I go back to my previous provider? Yes. Ask your original provider to restore your service, and demand in writing that the company that switched you cover any switching costs and refund everything it charged.

How long does it take to resolve? Sorting it out directly with the companies can take weeks; a complaint to a regulator can take months. That's why you should start right away and keep every piece of paper: time is on your side only if there's a paper trail.

In short

Slamming feeds on two things: your details and your inaction. Deny it the first by confirming nothing over the phone, and deny it the second by acting as soon as you see a sign: stop the switch, complain in writing and ask for proof of your consent, and escalate to the FCC, your state utility commission, or your state attorney general if needed. Check your bills every month, lock your cell number with your carrier, and report the numbers behind these sales calls in the NoCall spam numbers directory.
