Incorrect amounted debited from account

Multichoice ********ly deducted R2 500 off my account. I called them the day I received an sms saying that R2 500 is scheduled to be debited in the 1st. I was assured by the consultant that he has stopped the debit order from their side and I am to pay them manually for the services rendered. This morning I wake up to find out that the ridiculous amount has been deducted from my account. Now the inconvenience of calling my bank to arrange for the debit order to be reversed. Moral of the story DO NOT go the debit order route....it’s like allowing people to help themselves to your money!
