unknown number on my cell phone

This number called my land line when I wasn't home, and the caller did not leave a message.

They called about 'my credit card'. Didn't say which card. They were going to help me get a better rate.

Automated voice says I qualify for a lower interest rate on my credit card didn't state which one. Voice says press 1 to speak to someone about lowering my interest rate. So I hit 1 and a male voice answered heavy middle eastern accent funny thing he says "I'm fine thanks for asking" I never asked!  Once he was done with his script I asked how he knows I qualify when I don't even have a credit card that's when he said go [***] yourselve [***] and hung up quickly. I called back and a recorded message answering saying if you wanna be removed press 1. It then says it will take 48 hours to remove me. SCAMMERS SCUMMY SCUM SUCKING SCAMMERS
