Irregular Debit Orders - Take when you feel like it ???

So I decided to apply for a Capitec Credit Card. In this package I took a personal loan of R30 000.

Capitec however deducts money when they want to for this loan

November: Deducted 29 November December: Deducted today 21 December - I wish to thank you for taking this money out of my account the Friday before Christmas - my salary has not been paid yet. So I also have no fuel for the rest of the month.

There is no planning or scheduled date for deduction. Do you really just decide today is a good day for a deduction.

I want this sorted out and sorted out today. Or the only option is to withdraw all my funds every month so you can not take as you please.
