If this number calls you +447787767943, be as insulting and rude as you would like. This caller has just wanted to let me know about the discrepancy on the amount of tax I have paid and has offered to sort it all out for me. Just need to give my personal scammer my bank account details to repay the overpayment to HMRC.
It’s the elderly that can be caught out, my elderly mother was worried by a call like this last week, fortunately as we keep drumming into her don’t respond in any way and hang up. Ring one of her sons and they will check anything for her.
