Worst customer service

I have received the worst customer service from Fashion World Store at The Glen. I made a purchase for R700 on the 13th, the amount was debited twice on my account. I went to Capitec on the 15th to get a reversal on the pending R700. On the 18th they debited again and Capitec could not refund me because the money was already paid into the store account. I spoke to the store manager Nocwaka Lulu who put me through a lady from Head Office named Conny. Conny was very rude on the phone shouting at me even though I tried to explain to her that I want my money back and I want them to stop deducting money from my account. It seems now I have to change my card details to stop them. For how long will Fashion World stop deducting from my account. Three deductions in one week is definitely unacceptable. This was my first experience buying at the store and it is definitely the last. I will never buy at that store ever again.
