DSTV Multichoice

For the past one year after my DSTV Lock price contract ended I've been paying cash at Pep store or Shoprite all the time. Saturday i paid my Dish R510 cash as normal but to my surprise i got a debit order from my Capitec account of R475 from Multichoice and money went out to cater for that debit order.

However this made me angry because when i called Multichoice i was told to go and reverse the money but the question remains: who pays the R40 that the bank charges for stupidity? Not multi-ripoff-choice myself. Stop debit orders on my accounts as this make no sense to me at all and i want my R40 back from Multichoice
