Gary A Warren on Caller ID - "William" (Indian accent) from Tech Support (never said Microsoft) wanting to talk to me about home PC support - he called where I work (engineering consultant) - I told him it was a business that he was calling - "no sir I am not" he replies and tries to continue his script and even told him we have a company that provides IT support and he kept side stepping - I hung up.
Another call from area code 520 (Tucson, Az). No message is left but all of my unwanted calls from 520 have been for a back brace that I supposedly requested information on. Scam.
