Debt collection — Capstone Credit & Collection, LLC. (CO)

Didn't receive enough information to verify debt. I have disputed this collections account on my report from Capstone CR a few times, and I have asked multiple times for validation of this debt. I have not once received the information to validate this debt and I do not/have not ever had a contract with them. Instead of providing the information to me, Capstone CR has deleted and readded the collection to my credit report, all done during the week of XXXX XXXX XXXX. Now this collection that I have asked and asked to be removed, has started the aging process over. I do not want to be stuck with this debt even longer now due to their unfair practices.
