That is because they forward their calls from unused phone numbers. Your caller ID will show up as the unused number, so if you call back it'll say is no longer in service.
I got another call from this scam. When I politely asked them not to call me anymore (for the 100th time), they just hang up. Not only are they a scam, but they are rude.
I really want a t-shirt that says "I killed Scott from Credit Card Services" I think I could sell a lot of them. This is a scam. Scott from Credit Card Services is the worst kind of person. He calls me 10-15 times a month but does not seem to get the hint. I hope he gets raped by his own headset.
I am receiving frequent unwanted calls from this number. Press 1 to speak with a representative and the minute you say "remove me" they hang up on you. Press 2 to be removed from the call list and you are automatically disconnected, and the calls continue. Today's was a male recorded voice saying "Hi, this is Barbara...". It claims to be someone offering me a reduced rate on something that I don't care about, did not request, do not want calls about and I cannot get myself off of the list. Blocking the number now.
