Nedbank service has gone down the drain

Nedbank has lost the plot. It's new Internet Banking website doesn't work properly (why didn't they test it first?), they have been making unauthorised deductions from my account ("we are working on a fix", they say) and their complaints managers are useless and also provide the wrong information. Today I finally had enough of their shocking overall service (20 minutes in dicussions with the credit card call centre, to no avail) and closed my credit card account (with great difficulty, I might add). I have been a client for more than 30 years. Goodbye
