Horrible FNB Customer service!

I have been calling FNB for the past week after having app**** for the payment relief with Wesbank. I got provisionally approved with Wesbank and was requested to completed the process via the FNB App. Firstly the FNB App wouldn't even allow me to login in for days then when I called FNB I got no assistance instead I was being transferred all over the place due to the fact that I have no FNB account and the only association I have with them is Wesbank. Eventually I get on to the App and guess what, I can't complete the payment relief as I keep getting an error and can't move to the next step.. I keep calling FNB and yet again no one can help me, I'm so tired and frustrated. I've received some horrible customer service thus far is my time of need.
