Capitec Bank not safe at all

unauthorized debit orders from a company using reference SAGE PAY keeps taking money from savings account on the 30 April 2019 they debited R105 and i was able to dispute the debit order from the My Capitec Mobile Banking App, and another debit order took place today on the 15 May 2019 when i try to dispute the debit the dispute button on the App is grayed out and when i call the toll free number am told to go to the branch the last time i went to the branch i was told to use the App, this is totally unacceptable Capitec Bank is not safe at all.
