Same as everybody above. This company calls about my credit card, which I don't believe in and don't have. I've asked them not to call several times and am on the list. These days I try to keep them on the line as long as possible asking to be connected with different first names (Steve, Jason, Bill, etc) until they give up on me. Maybe if I waste as much of my time as they do mine, they'll give up.
A quick Google search on this number identifies it as "Credit Card Solutions." I'd be wary of phishing from any company who makes a point not to have a callback number.
Just got a call from them now!!! Exactly what everyone else said, on calling back "This is a promotional number....etc." They called my cell. If we can report them somehow, that would be great.
