I've had several of my customers call BT broadband support with a minor issue to only be called later in the day or the next day by "Microsoft" calling to help them with a problem.
It's either incredibly badly timed scam calls.. or someone at BT is leaking information.
There have also now been two occurrences of people who have moved into a house, had a line installed with a brand new number and not even used it and within a week had calls from "Microsoft" or their "Internet provider" about "problems" - Both customers reported to me that the scam caller has greeted them using their name.
I now keep a very close eye on those who have been scam called, how many were greeted with their names by the scam caller. Luckily the calls seem to have ceased in the last few months but at some level I think these "problem with your computer" scam callers are not entirely dialing randomly!
