serial abusive scam/spam/robo-piece of garbage criminal caller to my do not call number. This time, no info. provided of any kind, other than the number. but I call back, and a female robo voice tells me that the number that spam called me, is not a valid number. You see, he is desperately trying to steal personal ID to use in his other crimes which likely includes human trafficking. see at right, this is a MCI landline in San Bruno. the recording is typical criminal conduct. When this spammer attacks you on the phone, after blocking him of course, please contact the San Bruno Police Department.
