Poor service recieved at Matlosana mall Edgar's Shop

I bought 2 perfumes using pay just now at Matlosana mall on Saturday 07/02)2026. Pay just now deducted the first installment twice, I told the sales person that was assisting me that the money was deducted from my account and it went through. He said to me it's an error they will reverse it and I should swipe my card again. As it turns out I was charged twice for the same transaction, now matlosana mall Edgar's management is giving the run around about resolving the matter. They keep on telling that pay just now is asking for sleeps of which I keep providing and they took my phone number with the promise that they will call me and they never did. I went to check on them yesterday and today and still no joy. The mistake was made by their employee and now I have to pay for it, all I want is my money back. I can't be charged twice for the same transaction because of someone's ***********.
