Bad service

I have just experienced the worst service at Nedbank liberty mall. As the bank opened we were 3 customers waiting. I received my ticket number E003. On the screen showed a minimum waiting time of 5mins, I waited 15 minutes before a consultant called my number. Also my reason for going to the bank is I could not draw out money from the ATM. I have had this issue for the 4th time this year, when I go to the ATM it declined all transactions with error code 96. The ATM gives me this and asking me to contact branch. Now that I am in branch nobody knows what this error code means. About 6 months ago I have the same issue so the bank decided to replace my card. Now with the new card this is happening. I have had it with Nedbank and there ****py service. I will not be banking with them.in there new year.
