DO NOT CALL BACK. Yeah, they will call from 100 different numbers so, know who your contacts are or wait for a message. Likely they will not leave a message or if they do you will recognize the BS babble. Truly sad characters. Blocking at least one number every day.
Deep voiced overly friendly male voice soliciting donations for firemen and first responders. Told me I could donate $100, $75, $50, or $30 and asked me what I would prefer. I told him I would prefer that he go f..k himself. He actually laughed and told me to have a nice day. Total scam
