Studio88 double debit

I had a bad experience with Studio88 in PresidentHyper Krugersdorp. I bought Nike sneakers on the 15th of June 2021 and I used my bank card to swipe and it went through,for the amount of R750 00. On the 19th June 2021 the money came back to my account then waited for them to debit the money as I thought it was a technical error. On the 27th of June 2021 studio88 debited R750 00 twice in my account.i went to store with my 3months bank statement as proof but I was not helped, until I went again and got assisted by the store manager Thapelo who really assisted me until the head office called and told me they cannot help me until I go to my bank branch again to request another bank statement because on their side it doesn't reflect that the debited from my account twice. I mean my bank statement shows all the transaction what more do they want from a custome. I'm really not happy with their services and I regret and wouldn't advise anyone to buy at Studio88.
