RMB/FNB Private Banking with poor service once again.

Like once every other year we have to fight with RMB/FNB over debit orders. 3 months later after stopping and reversing debit orders and still haven't received my money back. On the online website it shows that they have been completed. "Mandate Received", but no action from FNB/RMB. Had a chat with an agent yesterday and promised to "escalate the issue" to the debit order disputes department. Today she mentions that she hasn't received feedback, she will send a second escalation. Tired of fighting with RMB/FNB now. Time to move
