DISAPPOINTED!!!!!!!!

I have been using capetic bank forever now and I AM SOOO DISAPPOINTED about the service received from Kopano Thale , she really does not know how to talk to customers(if need a call recording I will be glad to send it to you!!!!!) My issue is that the is a debited order that went out from my account of R89.99 I do not know what company is this.. because I have been out of South Africa for a year how can I have pass my details to a 3rd party if I have not been using this account.... KOPANO THALE said she will sent it to the back office and it might take 7 days to get details of this company REALLY!!!!!. I also sent an email last week 19 March 2018 haven't got any response Can this issue be sorted out now !!! IF this is not resolved out can my account be closed this .. I fail to understand that how can this company get hold of my banking details...
