FNB TAP AND PAY DONT WORK AND NO HELP

I have been battling for about 4 weeks with FNB complaints and the banking app channel to resolve the tap and pay function. They do not respond promptly and i get the same steps to try and resolve and nothing gets fixed. I have logged 3 complaints and called but nothing gets done. I am now looking at moving my entire portfolio with Investec due to the lack of poor service levels
