Not even bad service, just NO service!!!

I have paid up and closed every one of my Standard Bank accounts, and each one has taken months to get done, and for 2.5 months now I have been trying to close my paid up overdraft account, I have been into a branch 10 times to get it closed, and every time am told to check back in 10 days, only to be told the same thing all over again. Pass the buck must be Standard Banks mantra, \Moving Forward"no guys your service has been left behind in prehistoric times. """
