I dispute this debt because I do not owe this money. I terminated my contract for Internet service with XXXX in XXXX 2014. I received an email from XXXX stating that if I return their equipment before the closing bill, I would not be charged. At that time, I returned their modem using the packaging and shipping label they provided. My closing bill did not include any charges for equipment. I did not receive any bills or notices from them since ending the contract. 

In XXXX 2014, I received a letter from a company called XXXX claiming I owed XXXX {$100.00}. I called XXXX and their representative said they had no outstanding dues on my account and that they were unfamiliar with XXXX. The call was escalated several times and took almost XXXX hour to complete as they checked various databases. After that call, I contacted XXXX to gather more information about this claim. They told me it was for an unreturned modem. I put this claim in dispute. In XXXX, 2014, I received a letter from them confirming that the account was in a " disputed status. " I received a letter from another collection agency called XXXX XXXX XXXX XXXX XXXX on XXXX XXXX, 2014. There was no verification of the debt or any tracking information about the shipping label that was provided by XXXX. I received your collection notice today. 

I do not appreciate having to dispute this debt this many times as XXXX continues to sell consumer information to different collection agencies. Upon searching discussion forums, I understand that there are many consumers who have been troubled greatly by a similar error.
