There are lots of people calling to say they have been scammed by people calling from “Microsoft” or “Windows Support”, some even say they are calling from your Internet or e-Mail Provider. These calls are without a doubt scams.
Unless you report a technical issue, none of these people will call you & none of them will ask you to confirm your bank or card info.
Our best advice, if in doubt hang-up & DO NOT give any payment info to them.
