A "Microsoft Windows Support" person called at 7:08 EST with a destinctive Pakistani accent.
Normally, like "T" above, I do a "pay-it-forward" by wasting as much of their time as possible so it becomes less economical for them to scam other people. But it was a bit early and I just hung up. My record time waster was over an hour, continuously putting them on soft hold while continued on with reading a book. If everyone donated a little time scamming the scammers they would have a hard time retaining their employees.
The caller had a heavy accent and was calling about some computer virus scam. I played along with him for a few minutes and them gave him an earfull. He started screaming and then a woman came on the phone and started cussing as well. this is a scam.
