Business ProfileforMount Sinai

I am writing to respectfully dispute the bill that I received. My insurance paid -$6596 via claims submission I was billed a balance of $1167 And I disputed both since July 2023 but Mount Sinai sent the bill to collections. Firstly, I would like to highlight the inconvenience and frustration I experienced during the date and time of the service. I was forced to endure an agonizing wait of over 10 hours at the emergency room, desperately hoping to see a doctor. The lengthy delay in receiving medical attention was nothing short of unacceptable. Furthermore, I was also left waiting for a doctor to interpret my test results. Astonishingly, I was left without any resolution or guidance, as I eventually made the difficult decision to discharge myself from the facility. Shockingly, I wasn't even provided with any necessary paperwork or information before leaving.I sent an email to ************************* which is the person I was told to email when I called. I emailed ***** on 07/13/2023 asking for an investigation.why was I billed when I self discharged myself?I also submitted a copy of the bill on 05/05/2023 to our health advocate which is a free service offered by our medical plan.*************************** followed up weekly with Mount Sinai and she was consistently old the account is under review. On 09/19/2023 she was told the account was sent to collections suddenly. Which means the account was never under review. My complain was never under review and callously sent to collections which affects my credit score permanently?
