No drama please with my debit order amount!

It's my second month as a debit order customer at multichoice and already the wrong amount is scheduled to be deducted. Is that the reason why multichoice has been nagging me for years to switch to debit order? Clearly this was a big mistake. My advice to anybody thinking of signing up to the stupid debit order system, is that they should just stick to cash. The time and MONEY wasted fixing your problems is not worth it, especially for a service advertised as convenient.
