Closing Capitec Accounts

I went to the Mall of Africa branch today. The guy that was serving me had attitude as if his doing me a favor. I went there to dispute an unauthorized debit order. While he was reversing the transaction I asked him to stop the debit order in his response "if they use a different reference number they will be able to debit" I asked him how was it possible for a debit order to be processed without a debit check he told me that MTN doesn't have a debit check I went on to ask how can I prevent such an event from happening again in his response " go talk to MTN since they are the ones who make a request" I told him I don't use MTN never have I ever used MTN so clearly there is ***** that is happening in my name and I assume that my bank that I have used since forever will try to assist me in safeguarding my funds while MTN sorts out how the contract was created in my name in the first place. In his rude response " there is nothing we can do for you but you can close the account to safeguard your money" so in my response I asked him the process of closing my savings account and flexi account. He said I need to wait for any pending payments to go through so I can transfer my money somewhere else and close the accounts. So Monday morning I will be closing my Capitec Account and transferring my funds to a bank that can safe gaurd my funds since they cannot.
