Debit my account more that twice a month.

Webafrica is currently *****ing money left right and center from me, Debiting me 3 times per month saying this then that, blaming the bank. Went to the bank and they say its webafrica, so between the bank and webafrica I am out of pocket over R3k. The amounts are not even the same. Whattsapp chat does not work and the people on the chat means nothing. I want my money back but how the hell to get it back I don't know anymore.
