keep getting calls from this number and we dont have credit cards

We are on "do not call". Did not pick up when I said Hello once, so I hung up.

Received a call this afternoon from this number 239-482-3803. Did not recognize area code so did not answer, left no message.

I answered this call from unknown caller. Once again (closed to 12th time) it was from a company requesting for the "last time" for my chance to lower my credit card interest rate. I tried to speak with a representative to have my number removed, but the automated message said something to the fact that ___ logged off. Normally, I would not answer the call, but I am looking for work and am hopefully expecting a call for an interview.

This 239-482-3803 keeps calling me.  Very annoying!!!
