Complaint sub-issue: Threatened or suggested your credit would be damaged

I sent a certified letter to Hunter Warfield on XX/XX/XXXX explaining to them that they were collecting a debt that was not owed and untrue. That after learning about the debt that was not owed and was brought on by an apartment complex that tried to take a retired military vet for his hard earn money, we are filing a civil suit against the company that they say a debt is owed. As of XX/XX/XXXX I have not received a responds from Hunter Warfield INC. So I dispute these claims with all 3 credit agency, and as of XX/XX/XXXX I received a respond saying dispute not specific, verified and updated. But I did not receive any proof on how Hunter Warfield claims I owe the debt. I have proof that this apartment complex and Hunter Warfield INC are trying to collect a debt that is not owed. We lived in this apartment for 18 months, 12 months lease ( attached ) and we did n't sign a new lease because I was due for orders. So we went on a month to month lease and my rent increased by XXXX. As you can see our rent was XXXX a month ( we were only late once in the 20 months we lived there ) on the move in date, I was told to do a check list o all the things that needed to be taking care of. I was told it would, our main concern was or carpet was no new, and have some wear and tear. They told us not to worry about that, new carpet would be put in, but it never was. We also paid a security deposit of XXXX. 
Fast forward to our move out date, we got a notice of how much we owed and if we want a inspection of the apartment before we moved out, we had to sign and return paper. We did but we never got a inspection, they told me when I returned the keys, everything was good, and I told them to keep the security deposit to cover the 9 days for the month of XX/XX/XXXX ( XXXX ) and to just sent the remained balance to my current address. And from that day XX/XX/XXXX I had no concerns or worried that I owed any money to them. Fast forward to 11 days after we move out, we get an estimate, no a bill but an estimate for new flooring and carpet ( attach ). When contacting them I explain that they never did a walk through, when I turned in my keys and was told everything was good. The manger told me she would get back to me and never did. So I assume it was cleared and moved on. But now I have this collection agency trying to collect on a debt that is not owed. I 've attached my finally bill from them stating was was refundale ( XXXX ) and our rent owed for XX/XX/XXXX-XX/XX/XXXX for XXXX. Also no utilties that where due as well. I 've also attached final statement copy of them charging me, late charges on a bill I never received ( XXXX ) and month to month Charge of XXXX, rent for XXXX when we were charged for 9 days and now they charging more, for a balance of XXXX. They are trying to charge us additional charges for new carpet, cleaning and painting. We did not get evicted, we did not abandon our apartment. We just simply moved out and believed all was taking care of. If we were to do the math, we own XXXX XXXX not XXXX that is falsely being report on my credit. I 've attach all paperwork to validate my claim.
