Product: Debt collection

I was a loyal tenant at XXXX XXXX which later changed their name XXXX XXXX XXXX. My rent was never late and was turned in before the due date frequently. I never had any issues until I had a disagreement with the office manager. One afternoon she began putting tow stickers on all vehicles in the parking lot. A flatbed showed up and began hooking cars up. Once I noticed I checked my vehicle and noticed a tow sticker. i immediately took it off and went to the office to find out what was the reasoning behind this. The office always had two females in the main section who handled the majority of the work. They have a manager who has her own office on the side of them. I only say this because i have never had any interaction with her prior to this day. I entered the office and one of the ladies stated the manager was still riding around the lot applying tow stickers. I located her and asked her why she would attempt to tow my vehicle. She stated that multiple tenants were having their company stay over and they were taking up to many spaces so she was having any vehicles she didn't recognize towed. I was shocked and we began to argue because I knew she had no clue who I even was because she had never seen me before. She was severely unprofessional and we both left the conversation upset and clearly not fans of each other. This incident takes place just a few weeks before I give notice that I am not renewing my lease. I gave the proper information and time of notice and the two females in the office were completely aware. They had me fill out paperwork agreeing to the terms and everything was completely fine. I asked for copies but she stated they don't give copies. I told her I was closing on my house on the XXXX of XXXX and my lease expired the end of XXXX. She stated that they could possibly get a tenant for XXXX and I wouldn't have to pay rent and they could just keep my security deposit. I told her that was great news and we agreed that they could just keep the deposit. After I moved I received a letter stating I owed money all the way through the first week of XXXX. The letter was from the office manager. I immediately called and explained to her the agreement the other ladies in the office told me and that they had paperwork proving the agreement. The office manager laughed and stated the paperwork was misplaced and since she couldn't locate it I would have to pay. We then began to argue again. She then said she would mail me a new letter stating I did not owe anything but she was not giving me my security deposit. I agreed that was fine with me. I never received the letter. Instead she sent a letter stating I owed money for carpet cleaning fees and locks and that I breached my contract for leaving early. She stated that had a fee and that it automatically voided my security deposit. Every time I called her back she would not take my calls and even hung up on me once I stated my name. Approximately one year later I get a collection call. I find it heartbreaking how someone could hold a personal issue or grudge with a tenant and abuse their position just to ruin someone's credit. I am now attempting to get it removed from my credit report but having difficulty. I am frustrated because it is something I truly don't owe and now I might have to pursue it legally which is also expensive.
