Frustrated with Nedbank service

I have been with Nedbank for 43 years I am very disappointed with the service: My wife took out a new Mi goals plus account because on her old Mi goals account she had to pay for every transaction.

I have been trying every day for the last week to cancel the old Mi goals account, but it is impossible to do, imagine one week everyday trying to cancel an account but can't.

They tell me the account has a negative balance of 50 cents, and I must wait 24hours after depositing. After 24hours the account again shows a negative balance because transactions on the other accounts, SMS's and whatever Nedbank can think of is reflected on the old account, so I can't win. I want this account to be closed now not in 24 hours or next week please.

Yesterday I phoned a consultant, took 15 minutes to explain the situation and he put me on hold for 5 minutes or longer, the call disconnected. I expected the consultant to call me back because I did not want to explain myself to another consultant for another 15 minutes. but the consultant did not call me back. Is this good customer service?

Please close my old Mi goals account and if it show's a negative balance please use the money from the other accounts
