Complain

My mother has been trying to cancel her account with Edgar’s. She went to the store to clear it and requested for the account to be close. They gave her a WhatsApp number to send confirmation of payment and assured her the account will be closed and this was last year May. Around October a statement came in saying she is owing an amount R310 that she went back to the store and payed and begged them to close the account. Last week a statement came again that she is peeing R335. I have called and emailed Edgar’s and they told me to pay the amount and the will close it. It has been paid but still confirmation of the account being closed. Does this means my mother will be paying Edgar’s for life?
