Wish I had an option to opt out due to the Misservice offered

I'm a appaulled and frustrated by the poor service I received on a claim I made in October last year, which was partially paid. I visited a dentist, who opted to use an independent dental lab. And both claims were submitted in time and independently and only the dentist was paid. And I was contacted by the lab and I then contacted by the dentist who informed me that as of July of last year they submit their claims independently by law as they possess different practice numbers. I contacted the medical aid with factual information and was advised to collect both the quotes and forward them for review, which I have done 2 times already, followed up. The first time I was told it was declined. 2nd time no feedback which was in April or May already. The dentists admin said they can't help me. And as far as I know all the procedures I underwent we covered by the medical aid and funds where available. And the lab themselves have also submitted follow up claims as requested in their contact with the medical aid. As is the lab is instituting a debt hand over process on the account for non payment. And should I settle what legitimately the scheme is suppose to I will find no recourse. I'm out of sorts and needs these matter to be resolved. I have been grossly let down. Because from my understanding if a law is enacted it affects all parties involved in this case the service providers and the scheme
