i got a call from this number and a recording said it was from my credit card company and they would lower my interest rate to 6.9% if I hit 1 and spoke to the agent.  I don't pay any interest because I have no balance. I pay each month. I wanted to tell them they were a scam but they didn't answer me.

WARNING--BEWARE!! These callers are   B I G   credit card criminals, known as the card service scammers! Under NO circumstances, give these lowlifes your credit card number, or you will regret it forever!
