RMB taking incompetence to an art level.

An amount was put through my RMB card that is incorrect. I have been trying to get through to the dispute division at RMB/FNB for in excess of 15 minutes and have been put through to 5 different divisions, not one of them being able to help me other than referring me to another division. I finally put the phone down after being told that I was being put through to a division again that I had put through to, the 2nd or 3rd time, I really lost count. For Gods sake RMB this is not rocket science, please get your act together. This is absolutely ludicrous.
