Who called from 2156004485

I am getting calls from this number as well saying we are working out of our federal contract. I believe it is another stupid collect call we always get here at our office. One year people are saying it's a Verizon number and now in 2014 it's a federal government number? Yeah I highly doubt this is real....

This a hole called 3 times in a row

ENTERPRISE RECOVERY IS THE COMPANY. THEY ARE A DEBT RECOVERY COMPANY FOR ANY BUSINESS. IE: STUDENT LOANS, VERIZON, PPL, REALLY ANY COMPANY.

I answered and they said they were from PHH Mortgage...
I told them I don't know who they were...
