Showmax virtually *****ing from customers- double charge

So, I've had Showmax for a while, because it fits my needs for entertainment and my budget. Back in April my Showmax subscription was disconnected because I hadn't funded my account, so I get on the Chat function to get help. It didn't help, I called DSTV and an agent informed me that I should update my profile with a new email address through Google play and I was immediately back online with Showmax.

No in August I was cleaning up my Google Apps that I pay for, I realise that I have 2 Showmax payments for the same subscription. I check my bank statements and notice a payment of R299 and of R345 from April. I then reach out to Showmax, they tell me to go to Multichoice. I get to Multichoice they tell me to go to Showmax. I reached out to Google play and they refunded 1 month of the erroneous double charge. Showmax has refused to refund for the remaining 4 months of being double charge. I'm just appalled by their agents' behaviours and the ********* way in which these companies have treated me. Companies today are unable to 'Do Right' by their customers and I'm certain that it will start showing in their bottom line.
