XXXX equipment was returned prior to my being contacted by collector. Collector was informed that I had received a confirmation of equipment having been returned, whereupon he hung up on me. Meanwhile satellite provider began to bill me for service that was cancelled several months before. My new satellite provider had disconnected the equipment that was returned when my old service was discontinued. But, old provider did not send the boxes for return of their equipment for several months! XXXX was paid for all service I was provided and nothing is due to them.
