On XXXX/XXXX/XXXX, I went for treatment at the XXXX at XXXX XXXX XXXX XXXX in XXXX XXXX, FL. I provided them with a copy of my health insurance card and my driver 's license ( which has my mailing address ). They also took my tel # which has not changed to date. This means that in addition to all my health insurance information, they had a reliable telephone and mailing information for me. I received a bill from XXXX XXXX for the {$100.00} copayment on XXXX/XXXX/XXXX, which I paid. I did not receive any other bills but I did not find this unusual because in the past, the bills were sent directly to my insurance company and all I was usually liable for was the {$100.00} co-pay. In XXXX XXXX, I received a notice from XXXX XXXX XXXX XXXX, a debt collection company, trying to collect {$370.00} on behalf of XXXX XXXX XXXX for my visit on XXXX/XXXX/XXXX. I asked why was this still owing and they said my insurance company denied the claim. When I contacted my insurance company, I was advised that they had denied the claim submitted by XXXX XXXX because they submitted the claim late. When I contacted XXXX, they said that they were trying to contact me but the letters kept going back with invalid address. When I asked them what address they had, it turned out that they had omitted a digit from my apartment number. As a matter of fact, I received one statement in the mail from them around XXXX only because the mailman had another piece of mail for me and was able to determine what mailbox to use. Basically I believe there was a breakdown in information sharing between XXXX XXXX and XXXX. XXXX had my apartment number incorrect which is clearly not my fault since XXXX XXXX had the correct address that they used to bill me. Further, if XXXX had submitted the claim on time, my insurers would have paid it, hence there would be no reason to bill me. My insurers contacted XXXX in XXXX and filed a grievance on my behalf. The collection calls ceased after that. In XXXX XXXX, I received a call from Affiliate Asset Solution, LLC, who are attempting to collect the same debt. I also received a notice from them dated XXXX/XXXX/XXXX attempting to collect {$370.00} on behalf of XXXX XXXX XXXX. I feel that I should not be held responsible for this debt for various reasons. 1 ) XXXX submitted the claim late, hence the denial by the insurance company. 2 ) When we go to the XXXX we are not told who to expect bills from. Without my receiving a bill from XXXX within the claim period, I would not have had the opportunity to contact the insurers myself to ensure that the bill was paid. XXXX had stopped trying to collect the debt and apparently it has now been sold to a new entity. I feel that I am being victimized because of ineffective communication between XXXX XXXX and XXXX XXXX XXXX and because XXXX failed to submit their claim in a timely manner. I had provided all the information they needed to submit the claim and I should not be held liable because they failed to do so within the allotted time frame. I have since contacted my insurance company, XXXX XXXX, to contact Affiliate Asset Solution to file another grievance. However, I would like all collection efforts to cease permanently because I am not responsible for this debt. I do not want this negative action to affect my credit report and I do not want another credit collection company to be calling me in another year. I feel that my rights as a consumer is being violated as I am being held responsible for a situation that I had no opportunity to prevent. How can I be held responsible if an entity fails to do what they are supposed to do? I would love for this matter to be settled permanently.
