Capitec is a bunch of ******* - I have proof

So a couple of days ago on the 12th of Dec, I bought game time for a game that I play, the transaction was successful, Ref: Schiphjol-Rijk NL, and transaction type "Online Purchase". 4 days later, on the 16th of Dec, I got charged again by Capitec for that very same transaction, Ref: Schiphjol-RjikNLNL, and transaction type "Card Purchase". This means, I have been charged twice for the same transaction and up until today, the 22nd of Dec, I got no refund for the 2nd transaction. Anyway, I spoke to the company I bought game time from, they refunded my 1st transaction, but still, no refund from Capitec for the 2nd transaction. I contacted Capitec, but no reply. So over the weekend, I tried again, on the 19th of Dec, I bought game time again, Ref: Schiphjol-Rjik NL, transaction type "Recurring Card Purchase". 3 days later, on the 22th of Dec, Capitec went again and made a double transaction, Ref: Schiphjol-RjikNLNL, transaction type "Card Purchase". So not only now have I been charged twice for the same purchase, I have been charged 3 times for the same purchase, and no refunds. Every time the transaction type is different with the same reference. So my question is why the hell is Capitec charging twice for these transactions??? And still no refund from them. This bank is becoming bad. And it's not the first time they did this. The previous time they pulled this stunt, I had to go in to a branch to confront them, for which they refunded the 2nd transaction, but I had to pay for them to refund it, like what the hell??? Since when does someone have to pay for their own transaction? I am really disappointed in this company.
