A friend of mine received the same scam call (didn’t fall for it fortunately) so I decided to give them a ring, gave them some fake details to run through their script and eventually got a Monzo account number/sort code to pay my supposedly-outstanding tax to. When I pretended to make the payment and they obviously didn’t see it arrive they provided another account to try again, that one is sort code 236972 so not sure what that bank is (Revolut?). The call dropped after this, either it’s a technical issue or maybe they finally realized they’re being played.
I’ve reported that account number to Monzo, does anyone know what the other sort code is?
