I've just had yet another scam caller purporting to be from Microsoft. As usual I waste their time as much as possible and then tell them they are criminals, hang up and tried to report the number.
However, this time Check & Report wouldn't accept the number: 012815830862 - saying it was invalid. Clearly the scammers have been spoofing as UK numbers for some time, however this seems to be a new twist in that it initially looks like a UK number but clearly isn't.
Firstly I should have been able to report it, but even better why aren't such numbers blocked at source, i.e. if the caller's number is not valid for the country (especially if in the UK) then the call should simply not get through. If this could also prevent the calls coming from overseas using spoofed UK numbers then everyone would benefit.
