Called for a free upgrade from 4G to 5G and asked for email address.

Claims to be from Three, or at least wants to talk about my number which used to be with Three, when asking them to confirm any details about myself because I don't know who they are, he hung up. I would suggest that this is quite a dangerous scam and should be taken quite seriously
