Call is from "Credit Card Services" (company doesn't exist) wanting you to give them your credit card information. As soon as you start asking questions, they run scared and hang up. Make sure you report this and file a do not call complaint to fcc.gov. Maybe if everyone took the time to file a complaint, the calls would stop.
If you are getting the call on your cell phone, the call is originating from the internet. You can go into your cell phone account and change a setting that stops calls from the internet.
