Poor Service and feedback regarding Claim

I am posting this to see if this is not a faster way to get complaints through to Discovery, long story short I have been battling 2 months to get a claim of under R300 approved which was used in Hospital, Discovery claims they need the correct procedure codes to process it but it seems like the odd 8 queries I have logged every one fails to read page 2 of the invoice where this is clearly indicated, after 2 telephone conversations and 5 emails where I have requested to speak to only one person so that we can sort this out I keep getting replies that \We need more information"and then we are back to square one. I have even rep**** to the customer survey after the last call that I am not happy and my issue is not resolved and again I am being ignored. The last phone conversation I was promised I will have an answer within in an hour"
