Product: Debt collection

Received a call from GLA collections in ref to a medical debt for {$190.00}. XXXX, representative from GLA, informed me that the debt was from XXXX/XXXX/XX/XX/2014 for XXXX XXXX XXXX. I explained to XXXX that I would pull the EOB for that date because I had some issues with my insurance in paying items and I would get back to him. I pulled my EOB and determined that the service for XXXX/XXXX/XX/XX/2014 was in the amount of {$95.00} and my insurance had paid it in full. I faxed a copy of the EOB and all procedures done on XXXX and faxed it over to GLA. I then called XXXX back and explained that the service for the date of XXXX/XXXX/XX/XX/2014 was covered by my insurance company. He said that the amounts did not match, and proceded to hang up on me because I refused to pay the debt. I tried to explain to him that i was not going to pay for a debt that was incorrect in their system. Again he decided to argue with me instead of trying to determine where the issue was. I finally spoke to a supervisor that was able to determine that the bill was from a different date and not the XXXX XXXX was stating. 
I received a call from the auto-dialer on XXXX and was put into XXXX 's vm, but I did not leave him a message, and attempted to call the agency back to see what they were calling for only to find out that the office was already closed. I called back again on XXXX to find out why I was receiving a call from them because I had already paid the debt, or so I thought. I spoke to a lady and asked to speak to a supervisor but the line was disconnected. I decided to get my ref # and information together and called back. I was transferred to XXXX. XXXX proceeded to argue with me instead of listening to my simple question of is there a way to track the ref # I was given to see if there is an issue. XXXX said fax the information over, and would not allow me to say anything at all. He even made a comment to the fact that people like to make up lies that its paid, and I asked what he said and he started to argue again and tried to hang up on me. I asked for a supervisor again and specifically stated to him that he obviously is not able to do his job, and it just seemed to set him off even more. I spoke to a supervisor and stated I wanted to file a complaint and her response was I just did to her, but she was less than receptive to the information. This morning XXXX/XXXX/XX/XX/XXXX I receive an email from GLA collections that states if I have any further issues with my accounty I need contact XXXX. I returned with a response that I found this to be a poor choice since I filed a complaint against him with a supervisor and that he lacked communication skills. XXXX refused to validate the debt even after I produced EOB 's from my insurance company showing that the date in question was paid in full, he also continued to argue and stated that I refused to pay the debt. I would like for someone to additionally listen to the conversation between XXXX and I. The minute there was a question about the amount of the bill and evidence is submitted to them to show there is something wrong with the account, XXXX should have taken the time to figure it out instead of immediately getting hostile and hanging up on me. It took several attempts to get anyone in the company to look at it, and finally a supervisor took the time to figure it out. Never was a detailed bill sent until well after the issue was determined. 
The XXXX part of the complaint is while speaking to the supervisor she informed me that GLA had requested information from me and that I had never faxed it over to them. In the notes XXXX documented that the amount due in their office did not match what I had sent over so the documents I sent were incorrect. The supervisor could not explain what happened to the documents I sent or where they were located. Now my health documents are missing and no one can account for them
