Nedbank Bad Service

Hello. I changed my business banking details within Nedbank - changing name and account number. To date my debit orders have been incorrect for 3 months with me incurring almost R3000 in banking fees. The debit orders were set up by Nedbank.The business manager was supposed to meet me today at 15:00 at my office and I am still waiting - it's now 16:30. I received a email saying he was stuck with a client and still await. A call would have been nice. This is shocking service...
