After receiving 4 calls within 1 1/2 hours from this number, I answered to try to stop the calling. A man with a foreign accent, maybe from India, said he was from Windows and started asking questions. I told him to quit calling or I would report him. He then threatened to come to my house. I hung up. I will not answer again. I wish there was a way the phone company would help their customers to stop these calls.
I also received 4 calls from this # in about an hour. Finally answered to see what it was. The caller ID said Dir Asst. When I answered a man who sounded to have a Indian accent said they detected a serious problem with my computer - I think he was going to walk me through fixing it. But I just said Thanks for letting me - I'll take my computer to the shop and hung up. No more calls.
After receiving 6 calls in one afternoon, I decided to answer to stop the calls. They wanted me to address "Windows" virus situation. My husband told them we were going to take legal action and they still tried back. Very persistent!
