I just got a call also, showing on the Caller ID:
6:42 PM July 25
Like your call, it also sounded like a call center (noise in background). A man with Indian dialect speaking told me they are calling because there are 2 people using my wifi account for illegal purposes. The fact that the Caller ID on my phone said "COMCAST" is the only reason I didn't hang up immediately, though I was very wary. I stayed on the line a little longer and then he told me the names of the people who are using my wifi and asked if I know them. Next, he asked "Are you near your computer? I need to sign on...." At that point, I knew it was a scam as I suspected at first and I told him I know it's a scam and hung up. But it really threw me that the Caller ID said "COMCAST". It is easy to get tricked into thinking it is real and I consider myself pretty savvy as far as falling for a scam. I am sure someone with less security awaremess would believe them. So then I called Comcast to try to report it to Security. That was at 6:49 PM. I have been holding on ever since (40 minutes so far) with horrible music that is loud and painfully scratchy! It is not even easy to find out how to contact Comcast security when I searched on the Xfinity site. This is unacceptable! Beware of these calls!
