Vodacom Sucks

And my struggles with vodacom continues!! Just received a new statement yesterday and still there are charges on which should not be. They insisting that I pay the penalty for reversed debit order but they took off more than I authorized so how is that on me!! I even paid the premature cancellation just to be done with them and still things are not at an end! I will now once again only pay my actual FINAL installment and hope this will be the end of this matter!!!
