I suffer from XXXX XXXX XXXX. I obtained an XXXX system from XXXX XXXX to assist with my physical therapy. XXXX assured me that it obtained all necessary approval from my insurer and that it was fully covered under my policy and that I would not have to pay out of pocket. I was previously pre-approved by my insurer for another provider, but used XXXX 's services based on their assurance that this necessary medical equipment was pre-approved by my insurer, as well as the fact that they told me the other provider ( who was pre-approved as a provider by my insurer, thus i would not have to pay out of pocket ) could no longer perform the fitting of the brace because it no longer had an orthotist. However, XXXX never obtained the pre-approval and later sent me a bill for {$7300.00}, and I am not sure whether or not it is true that the other provider did not have an orthotist at that time ( I trusted XXXX at the time ). 
I disputed the debt based on XXXX 's prior assurances and representations, but XXXX failed to respond and sent it to a collection agency. I am disputing this debt with the collection agency as well. XXXX is claiming I owe them money, but I do not based on XXXX 's actions, false representations, and unfair dealing with me. I uploaded a timeline and better explanation of all of the events.
