Rude customer service

Absolutely disgusted by how I am treated as a nedbank customer. I requested to close my account on the 16th of October, because of attitude issues from their staff. On the first of November I was billed R210 again. Trying to sort this matter out over the phone you just get attitude from the consultants with no luck of changing the account or closing it. I will never be using nedbank again. They can open an account over the phone, but you can't change your plan or close it over to phone. Nedbank is the worst bank ever.
