Almost 3-4 times a day I get a call from this number. When I answer nobody is there. The calls are very annoying because most of the time I am at work when they call. Please can someone help stop this person from calling.

Got a call today from this number.  The voice had a thick east-Indian accent and stated the call could be monitored/recorded. He asked for my uncle by name.  I informed him that the last contact I had with my uncle was 4 years ago via email, and he had no phone number.  He said he'd delete my phone number from their list.

Not sure what the call was regarding... perhaps it's a collection agency?

Received call from this number. Man with heavy indian accent insisted that this is collection agency.

We continued to get a call 2-3 times a day in the afternoon. We want it to stop!

I get 2-3 calls per day from this number on my cell and there is never anyone there.  It is very frustrating and AT&T can't tell me where this is from and I don't want to call it back in fear that there will be some sort of charge to my phone.
