Who called from 4803271234

They call me 3 to 6 times a day.  i actually talked to someone yesterday and told them to take me off their call list!  It is apparent that they did not.

They call my cell number 2-4 times a day. No message is ever left and I will never answer a number I don't recognize. How do we make them stop?!

I forgot to submit their phone number.....480-327-1234

Argosy university

If you you actually talked to someone on the phone, what did the want ? That's kind of why were here. Any help would be appreciated.
