Poor Customer Care - No feedback

I have been pushed to placing a complaint on this platform merely because Greenstone Branch Manager hasn't bothered to get back to me regarding my query. I went to the branch, the business banker couldn't help and referred me to a consultant who informed me I will be penalised about R1 200 for closing my rental guarantee account and referred me to the Branch manager. The guarantee expired in January and now I learn its a 12 month investment account which matures in October which I never asked for. The manager said she will escalate to treasury and revert back yesterday and now I learn she's off sick and I have to start from scratch with Wilna. I have been patient with FNB. I called private banking and asked them to escalate but the lady told me she cant help with that. I asked for a complaints channel and she said there isn't one hence I have no choice but this platform. I am not going to the branch again to spend another hour waiting for nothing. I did what I had to do from my side. I drove all the way to Simmonds to drop the original guarantee, went to the branch twice countless calls. Please cancel this account and release my money with the interest it's accumulated.
