Well if it was my bank calling I'd be suing them for disability discrimination for phoning me (deaf). I've already tried the Financial Ombudsman on NatWest over deafness and phone issues.

I've told my mum that even if she thinks the bank caller to her is legit. Hang up. Wait 10 mins. Look up the bank's number on a statement she has and use a different phoneline to initiate her own call.

Thanks for sharing how this scam works. I hadn't thought of the dual prong approach. Evil scammers
