I got a call from this number saying my windows computer has some serious problems. It was a foreign language caller and the background noise was a call center of multiple foreign speakers all saying the same message in different ways. I told her to never call again and she said, " Hey lady behave yourself or I will blacklist your computer". Obviously a scam and not very sophisticated at that!
530-287-8505 called at 1211PM today. I didn't answer, they left no message. Caller ID said FIRSTSTEP TECH. I see this is a new number for the Windows computer technician fixing your computer scam. Will file a complaint with the FTC.
