Vodacome accounts systems are useless

Vodacom has managed to completely prohibit customers from having complaints resolved - after changing my contract to a completely unsuitable one and cutting off my ability to make calls, they are unable to reverse the migration or recharge my account, and I have to spend hours on the phone with call centre agents who have not been given sufficient powers to resolve. Vodacom is not appropriate for professional people who need to use their phones for business purposes - their systems are designed for people who only need the phone for social reasons and can hence do without making calls. Very disappointing!
