Complaint sub-issue: Information is incorrect

I rented an apartment at XXXX XXXX XXXX their address is XXXX XXXX XXXX, XXXX FL XXXX. The leasing term was of 11 months and 9 days as of XX/XX/XXXX until XX/XX/XXXX. I always paid on time and left the apartment clean.They stayed with my deposit claiming that the apt was dirty. I never disputed this ( even that was not true ) because there's a lady in that office XXXX XXXX XXXX who always mistreated me and everytime I went to that office I felt harrased by her. Now the main situation is that I applied to rent another house through another leasing company and my application was declined because my past rental experience with XXXX have me listed like I owe them certain amount. The new Leasing office said it shows on my credit over 1,000 of owed balance to XXXX XXXX. I called XXXX XXXX XXXX on XX/XX/XXXX and XXXX notifying them of the misstatement, kindly asked them to review my records as a good payer and that nothing is owed so they could remove that. The XXXX XXXX answers the phone acting like she doesn't remember me, or the request I made and tells me again that she need to look up my account and see. XX/XX/XXXX, XXXX never answered. I contacted the " corporate office '' listed on the website and told them the situation on XXXX and talked to XXXX she identified herself as a member of the corporate office and asked me my information and said she could see my ledger and my past records ( but that she could not give me any details ) and that there was a charge that was posted after I moved out. She said she will pass on information to the regional manager and that they are the ones in charge of fixing these type of issues. She said she can not give me information about the regional managers because they're not reachable, they never answer the same day and not always answer her emails. I asked her who were they so we could fix this discrepancy sooner and she only kept saying that she would pass along information. I complained about this rude lady to her and explained what I went through so she could please understand that this is not fair and the way that these XXXX person treats residents is unfair, disrespectful, unbearlable and unlawfull. On XX/XX/XXXX XXXX called me back ( know remembering my case ) saying that there is a discrepancy and that she will be forwarding the information to see what can be done to fix this. She does not give me details of the amount. TodayXX/XX/XXXX I called XXXX XXXX XXXX  and The response today from XXXX was that I had to wait for them to get an answer through email by Corporate to then get them on the phone and discuss and see what can be done. She said ( cutting me off in evry part of the conversation and being extremely rude ) that she understands what I am going through, and that I am desperate, but that I needed to wait for Corporate Response. That she is only following procedures. I asked her, and claimed her that if she could please treat this with a little bit of more sense of urgency based on that she knows there's been a mistake by them and just needs to be corrected so I can apply somewhere else to live. She started being very rude raising her voice at me and telling me that she told me already I had to wait. I told her that it is not fair what they're doing to me and that I will record every step of this process until it gets resolved, then she hung up on me.
