Who called from 8042209872

The number called me and didn't leave a message. I called it back and a recording said that "all of the circuits are busy please try your call again later. So scam more than likely

This number called my cell and left no message.

Called cell, did not answer. No message. Glad I didn't answer from everyone else's posts!

Repeated calls to cell phone - wants to talk about "how to lower your credit card interest rate"

Credit card marketing robocall- blocked the call but how does one prevent future calls from same organization ?
