Who called from 6822537151

A message was left about my car warranty was about expire.

The number called my cell at 9:15 am - didn't leave a message - they are not important enough - BLOCKED the number.

Voice mail, no message, called back and added to their do not call

Didn't answer, no message left

No message left. They are never going to reach me without one, as I simply do not answer any call from a number not in my contacts list.
Called back and pressed one to be added to their DNC list -- betting that won't do any good -- and then blocked this scamarketer.
