I got the same call stating he was with Microsoft I asked for a call back number in which he gave me 909-713-7131. I looked both numbers up he called from Atlanta but gave me a call back number for California. Thankfully I know not to fall for this kind of bull. But if anyone wants the call back number there it is. These people will never learn.
I have received two calls in as many days from Atlanta, GA. I let the call go to voicemail but they did not leave a message. I immediately called back but got a recording that the number was not in service.
The less conversation you have with these comedians the better off you are. Asking them to stop calling you is often an invitation for vulgar and belligerent remarks since they know you're not falling for their games.
