Impossible to make contact with Wesbank on all platforms

I had been struggling for a few days to register on the app to place notice for an early settlement, just to point out, the app is not user friendly as well as missing functionalities. I'd tried contacting the call centre but i end up on hold for extensive periods, I'd sent an email but no response. Im highly disappointed with the service, it shouldn't be such a difficult task to contact Wesbank. Please could a consultant contact me?
