FNB Scan to Pay does not work and nobody seems to care

Ive now had several very embarrassing moments due to FNB: 1) I use their banking app's scan to pay as tap to pay does not work 2) It has now happended twice in the last 2 weeks where the funds show that it was taken from my account but DOES NOT show at the merchant, in both cases they were also FNB clients 3) I spend a long time on the phone to resolve this issue to ensure that the merchant receives their funds 4) I got a call today that in my last transaction, the transaction was reversed, even though I expressly requested that the transaction is completed. 5) I phone their call centre and the line is bad. I ask the lady to repeat her name for the 3rd time and she shouts at me. 6) Now after spending more hours on the phone they direct me to chat on their online app - you type your message, You get a message back you are no 2 in the queue, and a minute later, you have been disconnected, try again.

This is massively embarrasing and annoying
