Product: Payday loan, title loan, or personal loan

I obtained a loan from Mariner Finance in XXXX Tennessee. After paying on it for a little while I had a bad string of luck and got behind. They in turn placed my account with their attorney 's office ( XXXX XXXX XXXX in XXXX ) for suit to be filed. I contacted them and set up an arrangement, per the attorney, that if I continued to pay a set monthly payment they would continue the case so as not to obtain judgement on me. I faithfully paid for two years, missing only one payment with the permission of XXXX XXXX ( the branch manager ) due to me getting married. I paid extra the next few months to get caught up. The whole time Mariner Finance is reporting to my credit that I am current and paying on time. When I paid my XXXX payment this year I knew I was getting close to the end. Mariner had my total at {$320.00} and some change but I knew that the attorney 's amount was a bit different due to fees and court chargers. I called the attorney 's office in XXXX of this year and they informed me the TOTAL balance ( fees, court cost, and the remaining balance of the original suit ) was {$110.00}. I called Mariner back to again make sure. They said that they would balance their books to the attorney 's total because that is what is truly owed. I called the attorney 's office starting XX/XX/XXXX of this year to confirm the balance and to see how I could pay the remaining balance. For the next two weeks ; myself nor Mariner Finance ( whom I had contacted to see if they could get an answer since they would not return my calls ) could get them to answer a phone call, return a phone call, or even return an email sent by the branch manager for Mariner FinancXXXX. On XX/XX/XXXX I finally was able to get a hold of the Law Firm and pay them the remaining {$110.00}. I was given a receipt showing final payment and the date of XX/XX/2019. A few days later I received a PAID IN FULL letter from the attorney 's dated XX/XX/2019, that was sent to XXXX County Court asking them to dismiss the case and that the matter was paid in full. Then the first week of XXXX I had an alert on my credit that Mariner Finance reported that I was 30 days late on a payment and that my balance was {$320.00}. My payments were due on the XXXX of each month I paid XX/XX/XXXX with the FINAL payment. That is only 13 days NOT 30!. I called and spoke with TWO managers who told me to contact the customer care line at their corporate office. I called several times and NEVER got a return call. A week later I called the XXXX Tennessee branch and was directed to the location that the area director was working out of that day. I called and spoke with the area director who explained that he was out on vacation the previous week. After speaking with him and sending him a copy of the PAID IN FULL letter he stated that he would get with the corporate office and get it taken care of and to give him two business days to get it done. That they were going to waive the " remaining balance '' because my letter does state PAID IN FULL! Then on XX/XX/2019 I had ANOTHER late payment hit from them on my credit report showing that I am now 60 days past due! But how can I be 60 days past due when the debt has been PAID IN FULL? My credit has now dropped 55 points in two weeks and has cost me a car deal that I was working on for a new car and I can not be on the mortgage for my house that my wife and I were going to refinance. It has been a full week now, I reached out to the area director saying that this was UNACCEPTABLE, and the only response from the area director was " I hope to reach out to you tomorrow ''. That was on Tuesday, it is now Thursday evening and I STILL have NOT heard back from him or anyone else from Mariner Finance!
