Double charged

On the 26th February, i visited the Mr price home/sport at Hendrick Portgieter to purchase items worth 2350, upon paying, there was a gliche on the screen however the payment went through but the cashier was in a rush to nock off she said to me it didn't go through, trusted her so i paid again and did not check my messages and banking app until i got home to see that i have paid 2350 twice. Okay i slept on it because it was late, i went again yesterday, i spoke to one of the managers there his name is Shihluke Mashimbye, he checked the transaction of the cashier that assisted me and could not find my double charge even though i could see it go out on my banking app twice. it didnt appear on my statement because it was still on pending state. so i could not send my banking statement. today, i returneed to the bank only for the bank to say they can't help me because money is out to mr price. Shihluke had promised to call me, which he did not. i generated my bank statement early this morning and the two transactions were showing since they had both moved out of the pending status. I emailed Shihluke who had promised that he will send an email to head office, it is now 14:20, I call the store to find out why this has not been done, he tells me he didnt get my emails, to top it off, he is not willing to listen but rude rude, even when i explain the frustration i encountered of holding waiting for him on the call for 5min with people launghing on the background, he jumps to defence mode and not listen. I have sent all the proof including proof of payments to show my money went out twice on 17:48 and 17:49. I am not sure how else to approach the refund of my money as this is really causing me so much convinience because when i paid we were all in good spirits but now that i want my money i am getting a run around and no assistance at all. i am utterly dissapointed at this store and how they lack agency to such critical issues. a 2350 is a lot of money, i should be getting my money back instantly, but you are here causing me a headache, i need my money back Mr price urgently.
