I received a call from them a few minutes ago, and last night I received a call from a number with the same area code, but I have that number saved to go automatically to VM. Guess they're trying to pull a fast one.
Just got a call from this number too. Didn't answer, and they left no message. I've got Verizon so I don't think it has anything to do with any specific cell company.
I was getting the same call on my iPhone. I took an online survey too, after about the 5th call I downloaded an app called "youmail" that let me set up my phone to sound like a disconnected number, they called once after about 2 weeks ago and so far so good. Hope it stays that way.
