Frustration Over Unpaid Account

I am writing to express my extreme frustration regarding the unpaid balance for my son’s anaesthetist from his procedure in May. It is now November, and despite my numerous inquiries with GAP since then, this account remains unsettled.

I have been a loyal GAP member for a reason: to ensure that such shortfalls are covered, yet here I am, facing threats from the doctor about being handed over due to this outstanding payment. This is unacceptable. GAP has settled all other accounts promptly, but this one seems to have fallen into a black hole, and I cannot understand why. I have sent an email out every day for a week now and I am just getting ignored. No one has the decency or capability to respond to an email or sort out this unpaid account.
