computer voice--British--saying this is Sara...about your credit card...

Received call from 818-663-9472, re: my credit card rate. Hit 9 to get a live person. When he answered and I said I didn't want these phone calls on my cell phone again, he hung up. Called back and then got a menu that said press 1 to opt out of these calls. We'll see............

Caller ID says "Service call".  I was not home to answer.

just wondering who called
