DSTV Premium Streaming Costs being overcharged

I signed up for Premium Streaming on the 4th of July 2024. I was billed and paid the monthly subscription amount of R799.00. On the 3rd of August I was charged an amount of R,2397.00 which is equal to three months subscription costs. My account now states that I need to pay another R1,598.00 at the beginning of September. The DSTV app states that I have only one subscription package, but I am being billed for two or three subscriptions? Trying to get hold of anyone at DSTV to reimburse the amount is impossible!
