Poor service

I belong to a comprehensive medical aid plan that is administered by Discovery Health. I went for specialized dentistry more than 4 weeks ago. I have a stand alone benefit for specialized dentistry. On submitting the account for the specialized dentistry that was done and after having received the quote from Discovery ensuring from which benefit payment will be taken, payment for the account was taken from my insured out of hospital benefit and from my medical savings account thus depleting both of my medical savings and insured out of hospital accounts. I have made numerous phone calls to discovery to sort out the accounts and deduct the money from the correct benefits. I called the customer complaint department last week and I was told that the problem would be sorted out soon. To this day, no progress has been made and in the meantime I have to pay cash for prescription medication while knowing that I still have thousands of rands of medical savings and insured out of hospital benefits left. My next step, I suppose would be to contact the medical aid ombudsman.
