Complaint sub-issue: Attempted to collect wrong amount

I moved to The XXXX on XXXX in XXXX, Ohio in XXXX, XXXX. They are owned by XXXX XXXX XXXX. I broke my lease and moved out XX/XX/XXXX to relocate out of state with my employer. I have email correspondence with myself and the then property manager who is no longer with the company saying that they had found a new tenant and that I would only need to pay a pro rated rent amount for XXXX. I never received a bill regarding this. 

In XXXX, XXXX I moved to a new city and my current landlord reached out to The XXXX on XXXX to do a typical rent history check. They never mentioned anything about past due rent to him. Several weeks later I was contacted by a collections agency regarding past due rent for The XXXX on XXXX of {$2100.00}. My regular rent there was {$1300.00}. {$2100.00} is not pro rated. He informed me that this was for 2 months past due rent ( which is also incorrect ). I disputed this and sent him the emails between myself and the then property manager regarding the pro rated rent. The collections agency never contacted me again so I assumed the issue was resolved as I had submitted proof. 

I am relocating out of state again in XXXX, XXXX and applied for a new apartment. The rental agency informed me there was a collection for past due rent at The XXXX on XXXX. I reached out to the collection agency to dispute this as well as The XXXX on XXXX. My efforts to have a conversation with the new property manager,  XXXX, were dismissed as he talked over me and did not really give me a chance to speak. I told him I wanted to send him the email correspondence between myself and the former property manager. He said he would like to see it. He spoke with his colleague and they agreed that I was not entitled to anything that was written in the previous emails and went on to say that I had corresponded with the previous property XXXX past XXXX, XXXX. This is false, I believe whatever alleged emails they have between myself and the former property manager ( which they will not allow me see ) have been tampered with and/or do not exist at all. 

Important things to note : - I never heard anything further from the first collection agency regarding this once I submitted my proof. 

- This has been with the current collection agency since XXXX, XXXX. I have not received any correspondence or voice messages about this. I have however, received random calls from unknown or blocked numbers that NEVER leave a message which I later found out were from this current collection agency, Hunter Warfield. There were never any messages or written correspondence left. This is a violation of FDCPA rules. 

- I have had an unblemished rental history since XXXX when I first started renting and my current landlord can attest to my on time rental payments. I move for work quite often and there has never been an issue on me paying rent until a new tenant is found. Especially since I am usually moving 100 miles or more because of work. The XXXX on XXXX has been the only issue. 

- I am not disputing that I owe The View on XXXX, I am disputing the amount given the correspondence between myself and the then property manager.
