We sent back XXXX XXXX XXXX equipment on XXXX XXXX and XXXX XXXX XXXX received the equipment a day later on XXXX XXXX. Debt collector started calling me on XX/XX/XXXX a few times a day. Finally I answered the phone on XX/XX/XXXX. Told them that I do n't owe anything, I sent the equipment back to XXXX XXXX XXXX and they should contact XXXX XXXX XXXX. Told them to stop harassing me. Instead of contacting XXXX XXXX XXXX they kept harassing me by calling a few times a day. On XX/XX/XXXX I answered the phone and told them the same thing again. Then I got a letter from the debt collector to pay or dispute. Which I 'm disputing it. I called XXXX XXXX XXXX again just to make sure that I did n't owe anything, which I do n't.
