VODADOM WORST NETWORK TO DEAL WITH

About three to four months back I took to hello Peter to complain about VodaDom. From being a seevice provider I would highly recommend I would now give them 0 recommendations, lately EVERYTHING IS AN ISSUE, call customer service and you get sent from pillar to post. I already canceled one contract a few months back and now looking at canceling my last contract which I have had for about 10 years, for the past two months they have not debited my account and now my name is in the red, they suppose to debit my account every month on the 27th and this is the 5th time my name is in red with vodacom because of thier incompetency, I'm sure other providers wouldn't mind at all debeting my account on time unlike VodaDom. I been trying to upgrade for over a year and thanks to VodaDom always keeping my name in the red I couldn't get it right so I done my upgrade already with another service provided, so VodaDom has already lost out, I'm left with one month to month and honestly is it even worth it?
