I had two calls in quick succession early one morning last week, each from the same number.
The first scam claimed to be from Microsoft to help me with errors on my computer.
The second scam claimed to be from the TPS, offering to help me stop nuisance calls.
Amusing as I found it, it did occur to me that vulnerable people who really had signed up with TPS might just be taken in by the second of these. I have no idea what the aim of the call was, other than it was obviously a scam.
