Poor service on claim still not resolved

I've been admitted to Olivedale Hospital to have an impacted wisdom tooth removed. I phoned Discovery for a reference number and was notified that there will be a membership portion that I will have to pay directly to the hospital upon being admitted of R2 850, which I paid. Discovery informed me that because my Medical savings account was so high, that I can claim this R2850 back via a special claims form. I sent the special claims form together with my proof of payment to the Discovery claims department on 14.08.2015 via e-mail. They responded that they also needed the hospital statement to process the claim. I sent the statement with the original document of the previous e-mail on 19.08.2015. Five days passed,no response. Phoned Discovery, where the lady said she will escalate the query - Call ***, this was on 26.08.2015. No response. Called again 28.08.2015. A gentleman informed me that the previous girl did not attach the docs, he then escalated the query again and said he will call yesterday Ref ***. No response. Called again. Another lady said that the queries have not yet been opened and she also escalated the query. At my wits end and still not resolved!
