Cross Country Bank Harrassing me over a credit card debt that I never had with them and using a wrong first name for me! Huntsville, Alabama

I have been getting harrassing phone calls from a Company saying they are Collecting on a debt that I owe from "Cross Country Bank". They keep referring to me as Shelly (a nickname used early in my childhood & not since). They claim I owe them over a thousand dollars and yet, I don't have credit cards, don't use credit cards & have never heard of this company before.

They claim I'm "pretending to be someone else". It's very bothersome & infuriating. I have now seen a long list of folks who seem to have similar problems with this company. Are they even a real company or some spoof hoping to milk money out of people who are too stupid to recognize that they never even had an account with them? It's worrisome to me & not sure what I can do about it!
