 I received a call which I called back several times with different people . 1st was a Michelle Williams stating I owed $650 in 2010 at an address I was at years b4! Then spoke to Theresa, Leon and Amy! Was told I owed $450 in 2010 at an address I did not live at, was years b4! Threatened me with court! I said... go ahead I have proof I didn’t live there at that time! I asked for a fax # to prove myself ! EVERYTIME they hung up! They said I did that in 2010 at an address I wasn’t at! I was at diff address for 2 years b4! EVERYTIME they hung up I called back! Asking for a fax #! Refused! Then would hang up! So beware !
