Nedbank Disgusting Service

I am very repulsed with Nedbank for their action of taking funds out of my account without any permission or consent. It is very ******* that they seem to think they can just dip their hands into the clients bank accounts as if they own it, even though it goes against the Consumer Act. I have requested two reversals on the amount '******' out of my account and a week later I am still waiting. I am fed up of their excuses each time you speak to a consultant and the lies that it takes 48 hours to reflect back into my account. Since last Thursday more than 48 hours have passed and this is very frustrating as the funds were not theirs to touch in the first place. I have been a client with this bank for more than 11 years but after this episode I actually want to switch to a better bank as I don't trust them any more.
