Edgars, RCI take over fees

Hi. Can you please help me. I have an Edgars account and haven't used it for a while. I had No balances outstanding. Then In October 2020, I received my statement and it had R39 outstanding. I contacted Edgars and was told this is a mistake, it was when RCI took them over and by mistake this amount was added, they will rectify it. November 2020 the statement came and it showed now, outstanding R69. Again I phoned and they told me again they will log this and have it fixed. I asked them to close the account and they said I have pay this amount first. Since then the amount stayed R69. I have emailed them 3 times asking to get feedback as they have send me sms's stating that I will be handed over to an attorney. No response yet! However yesterday I received a message saying that I have been handed over. R69 is not much But I have Not agreed nor signed Anything giving permission that Edward or RCI may add any additional fees to my account. I have Never had any late payments or outstanding amounts on my account & now they hand me over for something I have not agreed to. I don't know what to do. Please can you help me. Kind regards Jessica de Bruyn
