I answered since it was a call to my extra line no one calls. Went thru whole credit card spill. I waited for operator. When he said hello and started asking questions, I politely told him that I think he was trying to reach an previous owner of the phone number. Shockingly, instead of a thank you, or at least goodbye, he hung up.
Got a call from this number today at 9:32 am. Caller ID says "Credit Services". No message left. I don't need any credit services, and am on the DNC list, not that it does any good. Idiots.
