Beware of Dischem Rosebank multiple claims on Medical aids

On the 31st I got meds from Dischem Rosebank and I was told there are no funds the medical aid is not paying which was puzzling as it is the beginning of the year and I knew for a fact that I had funds. I ended up paying cash only to see that the claim went through and the medical aid processed and paid. I have been sending emails to Dischem Rosebank for them to refund and have not received a response. So Yesterday I called and asked them to look into this transaction cause they received double payment. instead of refunding me or the medical aid, they put through another claim today with today's date for the same items I took on the 31st. This is unacceptable. Refund me or the Medical aid and stop claiming for items that I have paid for over and over again! I heard another person complaining about the same thing happening at Dischem Rosebank so this is not an isolated case.
