Who called from 3212140898

Phones and says that they have made several atempts to contact us over our credit card but wont give there name or credit company they represent.

Got a call from this number bubbling about my credit card...I have no idea what is this robocall is talking about...I registered my number in Do Not Call list but seems its not working :-(

same time, same #. refuse to answer cell calls of unknown origin thus have no info on what they want.

Call to my cell. Did not pick up and no message.

This one of two numbers that continually call my cell phone offering a way to reduce my credit card debt. My credit card has only a small amount on it. I am on the national no call list as well. Who enforces that no call list?
