Waiting for Medical Aid refund

In February 2017 a claim was processed incorrectly on my account. Before I claimed i did the necessary inquiries, and the telephone operator gave the wrong information regarding where this claim will be deducted from. The claim was thereafter wrongly processed and when I took it up with them, they listen to the phone call recording and confirm that the info given to me what incorrect. They promise to reverse the claim. I have made several telephone calls to the call centre but up till now, no luck . This is nearly the end of the medical year and I would like them to help me before the end of the year.
