Claim incorrectly processed and useless consultants

sent through a claim for dentistry which Discovery incorrectly processed. When I phoned 3 times to query the reprocessing of the claim as requested, they gave me no feedback on my dispute of the claim. They keep repeating what Discovery processed not realising that they have app**** the discount twice in error. Told them I wasnt interested in what they processed, go look at the invoice at tell me how the amounts correlate even by apportioning the discount against all tariff codes. I lodged a complaint and that was just as unhelpful. The complaints consultant didn't even understand basic maths that if a doctor gives you discount on an invoice and that discount gets apportioned across all the items on the invoice, then the amount paid must be what is also processed by Discovery. Discovery completely messed this simple claim up resulting in my refund being underpaid. It also doesn't help that there is no email service and can only speak to consultants telephonically. The only way to successfully resolve this is to send screenshots which I am unable to do as nobody has given me an email address. They are a useless medical aid who can't process a simple invoice. Still waiting for the claim to be reprocessed for the 3rd time but doubt that I will ever hear back from them as usual unless i phone in again. They promise 2 to 3 days to reprocess yet after 3 unsuccessful requests with no feedback I have resorted to cancelling my membership. I cannot deal with a medical aid that can't even get the basics right. It is not rocket science. If they don't pay out my money correctly after this final complaint, then I will take this matter up with the Council for Medical Schemes.
