Discovery not paying Biokineticist fitness check

I did a Vitality Biokineticist Check during a Wellness Day on 23 April 2015, for which I paid cash via EFT. I got an invoice from the biokineticist which I submitted via email. It was rejected for lack of a service date. This was corrected on the same day. The claim was again rejected because of a lack of an ICD-10 code. <br> <br> I phoned the Discovery Health call centre and spoke to a call centre agent who was quite unhelpful (Faizel). I then phoned the biokineticist who said that this was standard operating procedure and I should submit the claim to directly to Vitality, and no ICD 10 code was required. I phoned Vitality an they transferred me back to Jade in the Health call centre who wanted me to tell the Biokineticist to phone in etc. I called the Biokineticist again who said he would phone in to resolve the issue, and that he used the same invoices for the \last ten years". He didn't call me back in the allotted time"
