Hundreds of rands disappearing from my capitec savings account

At this particular moment in time I hate capitec bank with everything in me. I gave them a date to transact debit order from my account by 1st of every month but lately they taking my hard earned money for work transport fares any time they feel so. This week I had to ask them as my bank to borrow me transport fares but they told me about loan interest as if I recklessly spent my money where as I saved well enough to reach the next pay day.
