Cell C costs you more than what you signed for

This seems to be nothing new when I read other reviews of Cell Z. Yes with a Zee because they are very last when it comes to service. They will run their debit order randomly every month and when it is returned we pay it manually only to find that at the end of the month they run 2 debits. This means that either the bill gets paid twice or returned fee's double. The bank fee's on this, some months, end up being equal to the bill amount. Should Cell Zee not reimburse these costs due to their unauthorized debits, we will simply not pay the bill ever again and should they continue with legal action we will have no problem in fighting that tooth and nail.
