UberEats charging meals twice.

I ordered on uberEats on the 29/01/2020 I paid cash. On the 31/01/2020 when I was requesting Uber using a bank card, a notification came through saying pre-authorized payment of R160.60 has been taken out. I escalated the matter with uber support which they were not helpful at all. I told them I paid their driver and at work there's a camera that could prove that and the money was even extra that I paid as I had no change. I paid twice for the same meal. Now when I doing a follow up am told I can't make another complaint about this as it was sorted out. Nothing was sorted out. I want my money back, please kindly help me.
