The number appears to be a UK landline or mobile looking prefix with public lookup tools available, but reliable, event specific details are not readily verifiable here. Public facing reports exist, but definitive ownership or a clear spam classification for this exact number is not established. 1. Ownership/type: UK numbering tools identify the number’s type and range holder, but do not confirm a specific owner; it is presented as a UK number that could be landline/mobile, with the operator identified by Ofcom data in general lookups. 2. Online chatter: Multiple UK reverse lookup resources discuss numbers similarly, providing community reports, scam flags, and general warnings about unknown calls. The results are varied and not consistently conclusive for this exact number. 3. Association with abuse: There are general warning patterns about unfamiliar UK numbers and telemarketing or scam calls in the referenced sources, but no unequivocal, verified claim that this exact number is involved in spam or fraud. 4. Public exposure/leaks: The number is listed in public lookup databases and appears in tools that aggregate caller reports, suggesting exposure in public directories and scam databases. Specific leakage or data breach ties to this exact number are not confirmed here. 5. Call back advisability: Given mixed signals and the prevalence of unknown UK numbers in scam reports, it is prudent to avoid calling back until verified by a trustworthy, independent source.

12Calling non stop including from a non caller is number …. Basically some times 5/6 calls back to back…. i am not interested in their services!
Explained I dealt with accounts and ask what it was regarding, couldn't speak to me as not director, advised to send a letter, wow not impressed at my suggestion...as I pointed out anything to do with HMRC they will contact us directly. She hung up on me...
Anne from CFS asking for managing director about personal financial matter. Sales scam, do not put them through.
very rude. wants to speak to director about HMRC matter. she wants to speak to him directly. put phone down. looking forward to recving her call again to tell her where to go
Thought she had given up but she called again today. This time I flatly refused to put her call through due to insufficient information. She is now getting a senior manager to ring me. Bring it on .....

Rude lady called Anne wants to speak to director, when asked what its regarding, she won't say and says something about HMRC, obvious scam/ cold calling. Ignore her
Ann Lannister (CFS) repeatedly called back when I refused to let her speak to Directors. Very rude and would not give any info on what call was about.
Call from Anna, wanted to speak only to the director on a HMRC Trade Supplier matter.
Received call from Anne. Said she had to talk to Company Director on a financial matter. Told her we weren't interested in their services and refused to put her through to Director. She told me she will call back on Monday. I told her I would not put her through to the director on Monday and asked her to take our company off the database.
Repeated calls from Anne Lannister at CFS in Birmingham. Only prepared to talk to a director about a 'finance matter'. Complete sales scam, just tell them where to go.
