Makro don't care

I want to know why Makro makes the use of the Payjustnow service and have staff that can’t help the customer if something goes wrong with purchasing process? On the 26th December 2025, I went to Makro Carnival branch to purchase some electronics and groceries. Makro uses payjustnow I thought it would be easier for me to use the service. Upon arriving at the till I asked the cashier if payjustnow is working. The cashier proceeded to scan all the items and the amount came to R7288. I then scanned the payjustnow QR code and the money has been deducted from my bank account but the was a problem the Transaction didn’t go through on makro’s side. I had to pay cash because i needed to products since i was Traveling from Mpumalanga.
