Debt collection — Amsher Collection Services, Inc. (OH)

Debt is not yours. I called to cancel XXXX XXXX and internet in XXXX of XXXX. I was told to drop off the equipment within 10 days of the billing cycle and dropped off the equipment at a XXXX store as directed and paid my XXXX bill. In XXXX I received another bill for {$220.00} and I called XXXX to correct the bill. I explained to the representative that I had canceled service the previous month and turned in the equipment more then a month ago. At the time I was under the impression that the matter was settled but received a collection letter months later. I disputed the debt and the collection agency sided with me. Now over a year after, I received a letter from a second debt collector and disputed it as well. Now the debt collector sided with XXXX because I no longer can find my receipt
