Capitec bank has failed me

Capitec has failed to protect me as their customer.i called them about a debit order(ss-leg cover) that I did not authorise they said I should dispute or stop it on my app.i told them that they can no be stopped.I went to the bank they rudely told me they can't do anything but open another account on the same card...but immediately money goes in the debit order deducts before I could transfer into the other account. I have been suffering to fully pay my fees as I always run short...it's been almost two years Capitec hasn't helped me. the company is ********** and only works on Capitec I wonder if Capitec helps them to ***** from us...
