free plan migration that is not free

I've learned that Vodacom supplies their customers details to service providers that are not their service provider, "Vodacom Rewards" is run by "Mondo", who under false pretense calls and offer a free migration with better plan and data, they never tell you that free means they wave the migration charge and that the plan will cost you more, when you phone Vodacom they are very sympathetic on the phone but refuse to do anything except give you Mondo's numbers ********** 690 or ********** 666 which Mondo never answers. This is a **** and a complete ******* by a brand that should no better. I want my original contract reinstated and this manipulations and lies of Mondo cancelled. They are a bunch of ********* ***** and manipulators. Vodacom's handling of this is unbelievably poor!
