Bad, poor, ******* and *********** service network

Vodacom the worst service provider, I can’t believe I’m writing my third review complaining about the same thing because they so ***********, ******* and useless. I’m being billed for their incompetence and mistake l was specific when I asked for my number to be activated to prepaid which I have the paperwork to prove, they reactivated to contract then I asked for the contract to be cancelled never used the contract airtime which Sanele the vodacom consultant confirmed on their system does show it was unused but I’m billed R460 for airtime I never used why? I’m sic of this Network
