I was called at almost 9pm by female at this number. When I said my phone is on a do not call list. she said it did not apply to her. I told her that it was people like her that it was created.
I've been getting calls from an 877 number that belongs to Verizon (or a creditor who does business with Verizon). Today I started getting calls from this 515 number as well. Neither number ever leaves a message. I have not answered either the of these numbers, but according to another website this 515 number is a company "DBA Verizon" as well.
