Glad they didn’t catch you out. There’s quite a few phone scams out there at the moment, knowing what I’ve had and my work colleagues have spoken about.
Just in the last month, I’ve had a similar call about a Visa credit card, my broadband connection needing someone to connect to my computer so they can optimise the speed and HMRC who apparently after me for some fine or other. So far, my credit card is still allowing me to spend, my video calls are still going through and I’ve had no nasty brown envelopes in the post.
One thing to watch out for on phone calls is that apparently scammers sometimes stay on the line but play a dial tone so you think it’s cleared - then you call your bank but are actually speaking to the scammers. So try dialling from your mobile or another line, or phone a family friend first who they can’t imitate so that the line is cleared.
