Claims Not Paid

I've recently complained about bankmed not providing Dischem with the correct codes to process a claim, as a result I was forced to make a cash payment, the claim could not be processed by bankmed as the incorrect codes were on my statement, Annelize one of the consultants that deals with hellopeter queries call me to assist with my complaint, I advised her of the situation, well instead of Annelize requesting a statement from Dischem with the correct codes so my claim may be processed, all thats happen is dischem has submitted a claim which they will be paid for after I've already paid them and the blame game has started again, bankmed blames dischem, dischem blames bankmed, when it is clearly bankmeds fault.
