Product: Debt collection

In 2015  I was involved in an accident where I needed to seek emergency medical attention. I went to a med express facility to receive quick treatment. I was fully covered by XXXX insurance at the time and paid my co-pay and was told there were no other costs. I was never contacted by XXXX after that. I had even visited the location and other locations a few times after that and was never notified that I had a debt. I have just opened a credit reporting service account and was made aware that there was a XXXX dollar OPEN collections on my credit report. This is from the 2015   incident. I contacted the collector, TRANSWORLD, and simply asked that it be closed and it be removed from my credit score as I never owned that money. The woman said absolutely but she did want to let me know that there was another account in collections for {$19.00}. I told her I was upset because I was never contacted about it but it was {$20.00} and I would pay it quickly and be off the phone with her. She placed me on a long hold while she spoke to her supervisor and when she came back she told me that she had re-opened and reinstated the debt for {$190.00} from 2015  though it was closed and I was never made aware that this even existed. I told her that I was never made aware of this debt never contacted and I did not show it. I was very clear. She said that it is not their job to keep up with my address changes and it is my fault if I dont see that I owe a credit or something. I asked if I could have more information like where I was treated the doctor I had seen or any of that and she insisted that I cant. She again put me on hold and when she came back she said that she could give me the date I was treated and the doctors last name but that was all. I told her I do not owe this this should have just been closed and she kept saying she had to open it and tie it to that debt so it gets paid.

I told her I do not owe this this should have just been closed and she kept saying she had to open it and tie it to that debt so it gets paid. 
I said Im not going to pay it and I will talk to XXXX and see what they have to say and I asked her though why wouldnt I have been contacted if I owe this debt? I should have been phoned, emailed, or written about this. She said she had no answer for me. I insisted on getting an answer as to why I was never contacted. I said, if I never opened this credit monitoring account and if I never called into investigate that this would be a pending collection since 2015 for the rest of my life? And be affecting my credit score for the rest of my life? She then gave me credit score advice which I dont believe she is legally allowed to do And basically said maybe if I had been monitoring my credit score closer that this wouldnt have gone missed. I contacted XXXX and they said that Bill had been settled XX/XX/2015 and they had been notified that it had been paid on XX/XX/2015. So this is just been a XXXX open balance on my credit score since XX/XX/2015. That is unacceptable. My credit score has been affected now for five years without my knowledge and wrongfully. Not to mention the level of unprofessionalism and disrespect that I experienced when trying to get this solved is unmatched by and Ive had before. The woman and her supervisor whose names I have were inconsiderate rude wrong and really causing me emotional distress. I called XXXX to get my information and the woman had to talk me through my XXXX XXXX. I couldnt catch my breath I was dizzy and my night was completely ruined because I was having such a severe XXXX XXXX. The woman from XX/XX/XXXXinsured me that everything should be OK and she emailed over the proof that I owe them absolutely nothing and I should be cleared of this.

Im now concerned that my credit score will be forever effected by TRANSWORLDs mistake and I dont want someone else to go through what I went through with this woman, her supervisor, or this company ever again. You should not be harassed, attacked, and spoken down to by collectors.
