FNB Call Centre - Frustrating and no help at all.

I received a text message from FNB indicating my home loan payment was not collected. I have funds available and this is on debit order and therefore I have no idea why. I contacted their call centre - First call picked up someone who did not greet me but left me holding whilst engaged in a long personal call on another phone. I eventually hung up. second call got dropped whilst being transferred to the verification process. Third call, the call centre operator transferred me to collections who do not appear to take calls - Computer voice says leave message after tone - but guess what, no tone! Another option to dial one and someonw will call back same day. I tried this option yesterday and am still waiting for a call back. Tries agin today but was informed that the mail box is full.

FNB, you really need to jack up your call centre, it does not work and just causes frustration. I had also sent a message via the banking app but no response to that either. I refuse to incur penalties for a home loan payment that was not processed due to FNB's error especially as they make it impossible to contact anyone to sort it out!
