Debit order Dispute

Yesterday I went to Century City Branch to dispute a debit order, I explained to the agent the reason for the reversal and that I could not reverse on the app. The agent advised me that they are gonna charge me R60 as the debit order is 40 days + and that the amount will be in my account within an hour. To my surprise Capitec charged me R80.75 and the debit order was never reversed. I called Capitec this morning and only now that they told me that when you dispute a 40 days+ debit order there's a change of not being successful and that they will charge me regardless. Should I have been told all this info prior, I wouldn't have gone ahead with the reversal, I could have sorted out my query with Multi choice. I've been with Capitec for 12 years now and the service I received yesterday and today is just appalling. As soon as I get paid tomorrow I would be closing my account with Capitec as I don't have the energy to query every small detail of my account
