woman called and asked for my adult son. (adult son does not live at this address, but stops by on the way home from work.... but i did not tell her that part.) i asked if i could take a message for him. she asked if i was an authorized comcast account holder 'on this account at this address' (no address verification requested, nor would i have confirmed the address if she had asked). i do not have comcast so i said no. she told me that i did have comcast, to which i laughed and told her i have never been a comcast customer in my life. i again asked if i could take a message. she asked if she could call back, so i told her after 5. adult son stopped by for about 30 minutes after work and went home. adult son confirmed that his cell phone number was on file with comcast, not his mother's house phone. she called back at 8:30 pm and called me a liar for telling her that he would be at my house after 5pm. i told her i was not concerned with what a scammer thought of me and she has not called back from this number.
