Vodacom - becoming more useless than Telkom!

Its a pity you don't have a zero star rating option. I have been struggling for months to get a Vodacom contract cancelled, but they just keep taking my money every month. SMSs went to some 'primary number' that no longer exists and never was my primary number. And on top of this, they tell me that the number I am trying to convert from contract to prepaid will have to be recharged 2-3 times a week. Otherwise they will delete it and assign it to someone else because they have a shortage of numbers. WHO IN THIS WORLD buys airtime or data 2-3 times per week?
