COID has no service when it comes to paying accounts

I have tried everything to get my outstanding COID account paid. I treated a patient in June of 2019 and I sent through my claim via EDI to the COID department and it was accepted but has not yet been paid. When I call them they say I must go online, online does not work. So I go into their offices and they tell me their systems are down or that I am in the wrong building. When I go to the correct building they tell me their systems are down and that I must go online. When I go online my password does not work. When I send an email they tell me to reset the password and try again. I reset the password and do not get the new email to reset password or the website tells me that my information is incorrect. I email the people again, they tell me to go into the building. I go into the building and the whole process starts again. I have never seen such incompetence and no one takes responsibility. Every person I have emailed has given me another email to send the complaint to. That person sends me to yet another email which sends me back to the first email address. COID is absolutely pathetic and then they have the audacity to apologize for substandard service. It is not substandard, there is none. There is no service. I will never treat another IOD patient again as it is not worth the effort to get paid.
