Capitec processed double payments in an online purchase and never reversed it back into my account

I purchased sneakers online @ Zara on the 20th of December 2020 and the R799 was deducted on my account.Since I changed the number that is linked to my Capitec account, I check transactions on my app.I then noticed that on the 30th of December,Zara deducted R799 again from my account and I called the Capitec customer service line and told the consultant about this.She asked me a few security questions and told me she’ll escalate the matter and call me back.She never did. I had to go straight to the branch and I never got the help I needed. I woke up the following day with a notification on the Capitec app and it reads as follows: “Capitec Payment Correction +R799 into savings account,available balance is R48,66.” I never got my money back and when I checked my statements,the transactions don’t add up. I’m broke,it’s January I need the money.Please look into this matter.
