Not happy with Makro Alberton refund process

Completely not happy with Makro in Alberton. Went to buy a few things on the 14th of January and used the QR code (scan to pay). The first transaction went off my account, apparently didn't go through from their side. I had to pay again, making double transactions.

Went to the store with the proof of the transactions. Gave the supervisor my bank statements. A week went by without getting back to me. Eventually I went to the bank for assistance. 2 days after I went to the bank they called asking for my virtual card number, which I provided. I was called again and told none of the details i gave them shows on the system.

This is very frustrating and time consuming, as I have to run around trying to sort out this..
