Nedbank has no clue..!!!

I went to the Nedbank branch at North Cape Mall kimbeltey last week Friday to settle a credit card they are hassling me about. I deposited R5800 into the cash accepting ATM . The machine could Ted the money and all of a sudden the machine closes and prints me a slip saying transaction unsuccessful. I went into the bank immediately and was told to pick a ticket and have a seat like the rest of the customers. The more I tried to explain the staff what happened the less response I got. Eventually someone took a copy of my receipt and my contact number. Promised to contact me the next day as a credit card only balances overnight. Guess what. No call. I then went back on Monday morning 8h30 and was told to go to another branch. I obviously refuse and eventually someone came out and told me they would log a call. Now only.??? Why not on Friday.? And you guessed right. I still have not heard a word. Where is my R5800? Because Nedbank clearly doesn't know. I am now moving g ALL my accounts and investments to another bank seeing as Nedbank doesn't have a clue how to conduct business. Customer service is the MOST Important par t of having a business.
