Super Frustrated with Showmax and DSTV Support!!!!!

I super frustrated with Showmax and DSTV support!!!! I have a Showmax account that I pay for via debit order. Lately I noticed that Showmax is debiting my bank account 3 times for 3 different subscription amounts. Called DSTV support (as there is no Showmax support!!)....sent from one agent to another until eventually I am sent to a Showmax chatbot that is absolutely useless! As we speak I have no where to get this 3xdebit order reversed!
