Edgars Closing of Account impossible

I paid my account in full in store at the East Rand Mall Branch on Friday 30/11/2018. I asked the cashier that assisted me to help me to close the account. She asked a colleague to assist me to phone their head office. She told me that after she phoned head office that they could not assist me to close the account on the same day of the payment. I phoned them today 04/12/2018 and explained to the call centre lady that I want to close the account. She said that there is a charge of R60 outstanding on my account. I told her that I paid in full in store on Friday and wanted to close my account. She said that she had to transfer me to someone else as she could not assist me. I held on to speak to someone else for over 20 minutes and no one came back to me. I want to close my account and don't want any more charges put through but no one is willing to assist me.
