Nedbank is probably the worst bank!

Nedbank has the worst service ever. I changed to them 2 months ago because of all the services that were promised just to find out is a load of bs. In the 2 months that I have been with them there were 2 incidents and the assist was up to ****. First money was debited out my account from a debitor that I do not even know putting my account into a negative and I received a message saying I have to make payment into my account to cover the negative amount and when phoning customer service I was there is nothing they can do and should reverse it and wait until it reflects in a min of 48hrs and that was my transportation money, that did not bother the representative. I then yesterday went and deposited money into my account that I needed to pay for something important and the ATM switched off and displayed a message there was a technical issue took the money and before it was in my account and gave only my card back. I phoned them and was on hold in intervals for an hour with my airtime because I was desperate and needed to get it resolved but with no luck and they said I must wait 3 to 5 working days for the money which I needed urgently and with arrogance saying there is nothing they can do I will just have to wait. They also said the atm crew will contact me at nine today but I'm still waiting and nobody gets back me, so they don't give a **** because that money goes to the bank. I was at the branch where the money was taken and the something they don't give a damn about a customer as long as they make money from you. I am disgusted with this bank I should have stayed with the institution that I was with and that was treating me like a king and not like a piece of *******.
