Product: Debt collection

My lease ended with XXXX XXXX XXXX XXXXXXXX XXXX XXXX XXXX, Kansas on XX/XX/2021. A prorated rent portion was paid at the beginning of XXXX and has since cleared my bank account. On XX/XX/XXXX, I received a final account statement from the apartment office showing that we had yet to pay rent for the month of XXXX, and also included past due payments for water bills, penalties for those late bills and pest control charges. On the same day I received the statement, I immediately contacted the property manager, XXXX XXXX, to notify him that the account statement was incorrect, as we had already paid the portions related to rent and pest control. I stated that we would pay the utility portions. I did not receive an updated account statement. Not even a month after moving out, I received a collections letter from Consumer Collection Management Inc. stating that they were attempting to collect {$1400.00} ( the same balance on the final account statement ) that had been owed to XXXX XXXX XXXX  XXXX. Upon receipt of this notice in XXXX, I immediately contacted the collection agency and explained the situation to them. They stated that if I sent in an updated statement of account showing that we had in fact paid the rent and pest control then they would adjust the balance. Since I no longer live in XXXX, Kansas, let alone the same state, I can not physically go in to the office. The same day I received the collection notice, I attempted to call the office during regular business hours and no one answered the phone. I left a voicemail requesting that they call me back and never received a response. I continued to call multiple times a week and left multiple voicemails and never received a call back. On XX/XX/XXXX I received another collection notice in the mail and attempted to call XXXX XXXX ' office. No one ever answered or called back. On XX/XX/XXXX I called the office and spoke with XXXX XXXX, who confirmed that she could see we had paid the XXXX rent. I asked for an updated account statement to be emailed to me and she said she would work on resolving the issue. Later on XX/XX/XXXX, XXXX XXXX emailed me saying that they were going to contact their corporate office to try to resolve the issue. On XX/XX/XXXX I followed up with them since I had not yet received a response. On XX/XX/XXXX I followed up again since I still had not received a response, and the debt had now hit my credit report. I stated that I had made multiple attempts since XXXX of 2021 to try to resolve this issue and I have repeatedly asked for an updated account statement and they have failed to help resolve the issue. I stated that if the issue was not resolved by XX/XX/XXXX, that I would be seeking legal action against the company. On XX/XX/XXXX, XXXX responded saying there was nothing the company could do about the water bills and fees. I responded immediately and stated that I have never had an issue paying those amounts, but that I still needed an updated account statement since the rent and other fees had already been paid and those amounts make up over 50 % of the balance the collections agency has assessed to me. Over 50 % of this balance is due to errors on behalf of XXXX XXXX. In the same email on XX/XX/XXXX, I responded saying that if I did not receive an updated account statement by the end of the day, then I would be seeking legal action against the company. It is now the end of the day on XX/XX/XXXX, and I have received zero correspondence from XXXX or any of the other staff at XXXX  XXXX. This issue could have been resolved three months ago but this office has refused to help rectify the situation -- of which, is almost entirely errors on their part.
