Resurgent Capital Services Tel : XXXX ; Fax : XXXX sent me a notice that I owe Original Creditor XXXX XXXX XXXX {$660.00}. The current owner is now LVNV Funding LLC with Account XXXX XXXX. I have never done business with XXXX XXXX or LVNV Funding LLC . I wrote to them and told them the debt was not mine and asked for details or proof. They wrote back saying it was up to me to provide them with "... information detailing the nature of the inaccuracy along with any supporting documents to the following address ; Resurgent Capital Services XXXX. Attention : Correspondence Department, XXXX XXXX XXXX, XXXX XXXX, XXXX, SC XXXX. I called them and told them verbally ( XXXX time ) the debt was not mine and told them I can not give them any details because I do n't have any details or knowledge about this debt. Subsequently, they sent me written correspondence that my dispute of this account " appears to be duplicative '' and a notice that reads, " Please be advised that we will not continue to respond to duplicative requests for additional information. Should you desire to pay on this account, please contact us... '' The debt is not mine and I thought debt collection companies must provide proof of debt not just say they have verified it and not give you any information or detail? I wrote to them again asking for details and proof so I could present to my attorney to deal with them, but they say it is not up to them to provide details. They say it is up to me!? Please help.
