Product: Debt collection

I moved out of my Apartment complex  XX/XX/XXXX  not knowing I owed money for a security deposit. At that time the complex was called  XXXX   XXXX . I found out about the money owed when I used the complex as a reference for a new apartment rental which happened to be the same apartment manage company  XXXX . This was in  XX/XX/XXXX . I went to my old complex which was  XXXX   XXXX  asked them to pull up my file.  XXXX  the manager at the time.. showed I owed {$320.00} to   XXXX   XXXX .  He gave me a list of how they came to those figures. I still have that copy. By then this went to a collection agency by the name of  Rent Collect  aka  IQ Data.   XXXX  the one who filled out the  XXXX   XXXX   XXXX  originally. He called  Rent Collect  while i was in his office to explain to them that i was paying the complex and he was going to send my payment to   XXXX   XXXX  . They were even rude to him. After he got off the phone with them. We made a written payment agreement that he typed out on company letterhead that i 'd pay the {$320.00} with in 3-4  wks so that I can move into another apartment Complex by the name of   XXXX   XXXX  . We both signed it and I made my payments as agreed and I emailed them ever time i made a payment. Before the last payment was dropped  XXXX   XXXX  left the company and our emails were forwarded to a  XXXX   XXXX . I then asked her to send all the payments at once to  XXXX   XXXX  and she agreed. This was  XX/XX/XXXX . That same month I moved into my new apartment   XXXX   XXXX   after  XXXX   XXXX  verified that i paid  XXXX   XXXX . Fast forward 3 years later. I notice I have a new collection on my credit  XXXX  report.. It 's with  Rent Colle  ct/ IQ   Data. I  immediately dispute with the credit bureau in regards to  Rent Collect t he reason being. I 've already paid this account. This should be deleted. However It came back as verified. I was in shock. A week or so later  IQ data  XXXX  Rent Collect  sends me this old claim form submitted by  XXXX  dated  XX/XX/XXXX . This debt was was paid  XX/XX/XXXX  ... So they never even validated the debt. What he sent me I already had when  XXXX  gave me all those papers in  XX/XX/XXXX . So its outdated. Fed up with them because they are rude. I decided to contact the original complex. Since they are the ones who made the claim in the first place and are the ones who agreed to send to  XXXX   XXXX  so that I can move into a new complex. Unfortunately for me completely different staff work there now and they changed the name of the complex to   XXXX   XXXX  . I 've been sending numerous emails explaining the situation and even sending old email conversations with me from  XXXX  and  XXXX  and I can not get any one to help me. I 've been sending these emails since  XX/XX/XXXX  to  XXXX   XXXX  I hardly get responses. So last week I was getting to my wits end. So I kindly phoned  XXXX   XXXX  a week ago and verbally asked her to look into it. I gave her my whole spill again as I do n't think she even remembers me. She told me that she 'd call   XXXX   XXXX   to verify that payments were received but I have yet to get a call or email and rent collect/iq data is still on my credit files.. it 's been at least a week since our last conversation. I even sent a kind follow up email because I know people are busy and she  may  have forgotten our conversation. I know they have a copy of our signed agreement as well as copies of the money orders that i dropped off. Which i had already explained to her. My next step is to go down in person tomorrow. I just want this resolved and no one seems to care to want to help me. I 've sent them as much proof as i can dig up. I ca n't even trace the money orders now because its been so long. I refuse to pay something i 've already paid.
