Nedbank Credit Card Division Poor Customer Service

Bad Customer Service....I want to close my credit card that I paid in full as per the guy who gave me the settlement amount on Friday. He said that I must phone on Tuesday again in order to close my account. When I phoned this morning the first person I spoked to said that my account is now overstated with R6?? rand. She must transfer me to another department in order to reimburse me. From there on they transferd me to 3 wrong departments. Can someone from the correct department please get in contact with me!!
