Product: Debt collection

I received a letter dated XXXX from, XXXX XXXX, from Caine & Weiner. Telling me that I owe them the sum of {$2100.00}. 
They do not indicate what kind of business they are, only my name has been listed with his company for collection. I immediately respond back to the letter. I wrote stating that I moved out of the property I rented at : 1 XXXX XXXX XXXX, XXXX, Georgia XXXX two years ago, and that any debt owed, according to the laws in the state of Georgia , that then property management company, XXXX, would have informed me five days after my move out date, according to Georgia law , if I did owe any monies. I let him know I never once received any correspondence from anyone until 2 years after the fact from a XXXX XXXX. I put in writing very clearly that I wanted proof of any money I owe. I requested legible receipts with company names and phone numbers with the dates on the receipts so I can verify for my self that I owe any money. I thought that seemed very fair. XXXX XXXX, sent me back the most falsified document that had been typed up 5 days prior. The first thing listed on the document is that I paid XXXX deposit. That is incorrect and I can prove that I paid {$790.00}. As I'm reading this tenant ledger I can not believe that false, made up charges that I owe to his business. When I vacated the property, it was left in the exact same manner in which I received it. 
I merely asked for proof of the damages he claims I owe and he refused. Not only did he operate illegally under California law, but he falsified a document to get money out of me. Even if I did owe the money, the lease agreement shows a listing of various charges the tenant is responsible for and the amounts he lists I owe are inflated by 300 %. I wrote XXXX XXXX, two times informing him that I objected his letter and a falsified document with misinformation wasn't considered proof of anything. I factually can provide proof that I paid two contractors from XXXX, Georgia ; XXXX and XXXX XXXX, to repair any damages prior to moving out. I have the original receipts, with the name, address and phone number and amounts that I paid. I informed XXXX XXXX, that if he will not provide proof of his claim then I am considering the matter closed. Two days after I received this falsified document from XXXX XXXX he reported to XXXX, that I owed this debt and reported that I owe him {$2100.00}. The amount of money some how increased. I am reporting XXXX XXXX, has not only illegally falsified documents but took it upon himself to make up his own laws and disregard the laws where he operates his business and clearly Georgia tenant laws. 
I am in disbelief that my civil rights were violated and that my request for receipt of damages was denied. He thinks it's okay to submit a XXXX document that looks like it was typed up by a third grader is legal, because I know otherwise. I have never seen any business ever operate with the utmost unprofessionalism and steal money from people who don't owe it. I XXXX XXXX XXXX 's business : Caine & Weiner, and I was not one bit surprised to see so many negative reviews. There were too many to count. I'm putting into question why wait two entire years to collect on a debt because the women from XXXX, are by far the meanest bullies who threaten and intimidate. Trust me XXXX is by far the greediest property management company I've ever delt with. They ran to the court house every time my rent was late. The owner XXXX, wrote me the most threatening letter. XXXX, from XXXX, would have been at the courthouse filing a lawsuit against me if I owed them money. I'm not sure who XXXX XXXX, thinks he is but I want him investigated for illegally not following procedure and falsifying documents to get money from me.
