I already submitted a complaint against ATG on XXXX XXXX, # XXXX. ATG collection received debt that I owe. I contacted a credit consolidation service ( XXXX XXXX XXXX ) to negotiate with ATG for this debt. They are in the process of doing so. ATG keeps calling my work phone and sending me letters after XXXX XXXX XXXX sent them a cease and desist letter. Again, they called my work phone # on XXXX XXXX, 2015 at XXXX. This harassment has to stop.
