Product: Debt collection

In XX/XX/XXXX I moved into an apartment at XXXX XXXX in XXXX. I included my XXXX yr grandson on the lease so that he would have some place to live and not be homeless. Myn grandson suffers from XXXX XXXX XXXX, and after being off his meds it became impossible to live there with him. In XX/XX/XXXX he became very argumentative and making threats on my life. Also allowed XXXX other people to stay there. I did go to the police and was told there was nothing they could do because his name was on the lease and my only recourse was to file an eviction on him and the other people staying there. In XXXX I did file an eviction notice and served to him and the other people. In the meantime I contacted XXXX management to let them know what was going on and they agreed to work with me. I had the police stand by while I entered the apartment to get some things and see what damages had occurred, also I put in a maintenance request to go inside the apartment to access any damages so I could know what costs to expect for early lease termination. On XX/XX/XXXX the 30 day eviction notice became valid and the XXXX Police escorted my grandson off the apartment premises. On XX/XX/XXXX I took a check to XXXX leasing office in the amount of {$2000.00} for the additional days in the apartment to move furniture, personal items and clean-up and turned in the keys. NO other amount owed was told to me at that time. On XX/XX/XXXX, I got an email from XXXX XXXX telling me that I owed {$1300.00} for carpet replacement ( entire apartment ) bi-fold door and XXXX missing blind slats, also charging me {$60.00} for Gas which I shut the gas off with consumers energy on XXXX and they would send my final bill. I have taken responsibility for the damages for door & blind slats and paid my gas bill to XXXX XXXX. I am disputing the charges of {$770.00} for entire apartment carpet replacement, when only the room that needed to be cleaned or replaced was the bedroom my grandson slept in, and if I was told to get the carpet cleaned I would have done so, but I was never told to do this because my deposit {$1500.00} deposit would not be returned. I contacted the XXXX XXXX XXXX  about this matter and was told to pay what I was taking responsibility for and contact the XXXX XXXX XXXX to discuss the disputed amount. I did contact XXXXXXXX XXXX  billing and spoke with XXXX and she was willing to make some adjustments to the {$1300.00} after she had a chance to apply any payments that had been made. I tried several months to contact XXXX but was never able to speak with her again. XX/XX/XXXX was the last {$50.00} payment I sent to XXXX XXXX  ( XXXX ) and have never received any more communication. XX/XX/XXXX I received an email from XXXX XXXX about a collections account was on my credit file and it was from Rent Recovery Solutions for {$930.00}. To this date I have NEVER received a bill or any corespondence from them regarding this matter they have just attached this unfair debt to my credit which is very damaging. The resolution I am seeking is the unfair amount of {$930.00} be dissolved and remove from my credit profile and also my XXXX XXXX and XXXX grandson credit profile. I have paid over {$2300.00} for early lease termination to XXXX XXXX  and do not feel I owe any more. I have attached some supporting documents for my complaint. 
Regards, XXXX XXXX
