Cellphone Contract Service Cancellation NIGHTMARE!

Took out a cellphone contract with Vodacom in February 2016, not a single month did I miss payments — FF to February 2020 something as simple as requesting to cancel my contract service was turned into the stuffs that nightmares are made of. 6 months since the expiration of my cellphone contract with no desire to upgrade or continue with a cellphone contract Vidacom has taken me to hell & back for something so simple CANCELING my contract service! 6 months later consultant after consultant @vodacom has obliviously continued to invoice me for a contract that was confirmed canceled, there was an unauthorized upgrade done without my consent, they even went as far as suspending my line before sorting out my queries! The DISTRESS! The INCONVENIENCE! THE HUMILIATION! Caused is unspeakable, the respect I've lost for vodacom as a business & trusted service provider is lost!
