XX/XX/XXXX I stayed at XXXX 's of XXXX XXXX with a tradeshow. XX/XX/XXXX I received a phone call from Allied Collection Services of XXXX XXXX stating I owed {$160.00} to XXXX 's of XXXX XXXX. I told them that I did stay at Ballys ' and if they could tell me what the charges were for, I would pay them. The gentleman told me he would mail them to me but I never received anything. On XX/XX/XXXX I received another call from a different person ( XXXX ) from Allied Collection once again stating that I owed {$160.00}. I once again asked for documentation which they said they would mail to me. On XX/XX/XXXX I received a copy of my credit report in which the {$160.00} debt severely degraded my credit score putting a mortgage for a new house in great jeopardy. I called XXXX of XXXX XXXX but they only keep records for 90 days and could not tell me what my bill was for. I called Allied Collections and paid the bill even though I have no idea what it is for since I felt like I had no choice. Now I possibly will default on a new house offer and lose a {$10000.00} down. I paid the debt with interest and a credit card fee and feel like I have no recourses. I did n't even know I owed the money to Ballys and I 'm really not even sure if this is related to my stay. I had an XXXX credit rating and no debt before this event and now I 'll probably have to tell my kids that XXXX 's has taken the new house from us ... ..
