Worse Claims process and notification from Bonitas!!

I cancelled my previous medical aid in 2019 and decided to move over to Bonitas because of some friends and colleges that said they are a some of the best Medical aids to join. So we took the next step and joined. Covid came didn't use medical aid that much and now in 2021 I need to go for a operation and and so far everything all good. Now I need to submit the claim for consultation at the surgeon and I've done the first one on 30 August 2021 didnt hear anything form them regarding the claim at all. on the 21 September I phoned the call center to find out whats going on lady informed me sorry the claim is not processed due to the attachment that they couldn't see al of the details. Then resubmit while on the call with the person who's assisting me. Phoned again on the 19 October 2021 because still didn't get any feedback other than we've received your claim submittion mail from a no-reply mail. So after some look the lady informed me that the claim is closed due to ICD-10 code that is not present on the quotation. No response from claims to mentioned anything about that or to state that the claim is closed and not processed due to following reasons. The reason I moved to Bonitas was exactly the same reason because of the previous medical aid that also gave poor service. So it seems like its a common thing with medical aids to only be nice and useful for the first 6 months and after that they just need your monthly contribution and stuff the rest. Either Bonitas need to resolve this poor service or they will start loosing more clients as that is not how a company must treat their clients. So pitch up and resolve this or I'm very happy to move again not a problem for me at all.
