Who called from 4439574690

constant cell phone calls from this number  which is a pay as you go and I didn't give out my number?
so annoying

I received a call from this number today stated that I owed them money for an AT&T bill.  We do not have AT&T and never did.  After telling the person this they continued to call back several more times.  Letting us know they had all day to call.  VERY ANNOYING....

This phone number keeps calling me and I AM NOT TAMMY!!!!!
