Caller type: Scammer/Fraudster
UNKNOWN CALLER 214-263-3521 called my National DO NOT CALL Registry listed number 3 times within one week despite a warning message stating FCC/FTC regulations allowed a $600-900 charge to any unrequested robo-callers and telemarketing solicitors. The first time both the number and "UNKNOWN CALLER" displayed and appeared in the digital log. Thereafter the number was hidden and only "UNKNOWN CALLER " appeared in the digital log. Each time the caller hung up immediately AFTER the warning message ended. The repetitive calling and attempt to hide identity indicates a probable scammer.
