I've been getting calls, heavy accent, from the same number, saying they're from "technical support". I knew it was a scam since even a contractor will identify the manufacturer they represent. Out of curiosity, I questioned him.
Q: Why are you calling?
A: About your operating system.
Q: What operating system? What version?
They gave me a wrong answer. I said I don't use that. THEY hung up.
I just received a call from this number, although I didn't answer the caller left a fuzzy message on the machine that said something like "I am from Windows, calling about a computer", which is nonsense. Definitely someone trying to scam personal information. Hope this is helpful!
Called me and said they were from the windows company. Said my computer was sending fraudulent information over the Internet. Wanted me to go to their website to fix it. He had a a very heavy accent, too hard to understand. I hung up but they called back right away, twice. He got pissed when I kept telling him I couldn't understand him. Hmmm maybe that is the way to handle it in the future.
