It's the old "Rachel from Card Holder Services" "Lower your interest rate" scam.
Press 1 if you want to mess with them, but NEVER give them your credit card number! Never EVER give out your credit card information to anyone who calls YOU! You have no idea who might be on the other end of the phone.
The gal I spoke with admitted she was calling from the Dominican Republic!
Called very early this morning and did not leave a message. I went ahead and blocked them from calling back. You call me early in the morning after I have worked all night and don't leave a message, you will be blocked.
I pressed 1 and they said they were going to lower my interest rate on my credit card. They wouldn't tell me which bank or credit card they were calling from. Definitely a SCARY phishing attempt. BE CAREFUL. Do not give these people any information about yourself.
