Vodacom - worst service provider

For four months we have been trying to cancel a contract with Vodasom, we have had to pay for an additional 4 months while the SIM card is not even active. As per a phone call on 30 April the outstanding balance needed to be paid and then the contract would be cancelled. We phoned again to verify that all was in order and that the contract is cancelled only to be told we need to pay for another month. Vodacom has to be there worst provider out there and we will never again deal with Vodacom!
