Terrible Service once again by RMB Private Bank.

Once again, I have to come here to voice my frustrations. I contacted the chat app to reverse/stop debit orders that have changed the amount. To my surprise, as much as the lady saw that the amounts differed from the d/o mandate, she still couldn't reverse them. Now I ask her to stop them at least. She agrees but stops only one. I contacted someone else, who apparently can't assist. I am an RMB account holder but my chats always go through to FNB Premium, why is that so? I need this to be resolved asap. I am tired of waiting for weeks to have my issues resolved if they ever get to be.
