Grossly misrepresented and blatantly ****

My wife recently upgraded her contract , the lady that called said she is representing Vodacom (actually representing Mondo Mobile) She grossly misrepresented and blatantly **** regarding the details and amounts. The contract my wife agreed to was for the amount of R1158 per month and not R 1648.01 After multiple calls to vodacom I discovered that the "rewards department" handled the upgrade i.e. vodacom speak for Mondo mobile, I contacted them directly (a very frustrating fact as the contract is with vodacom and not mondo mobile) and after multiple calls they discovered that the "claim" is valid (by claim they mean the lady **** and they want to **** money from us) now their solution is to cancel the contract, collect the device and make it my wifes problem to redo the upgrade. But I have a few questions: What phone should we use in the mean time? When will the contact be canceled? How will the billing be sorted out? Why they are not willing to cancel the current incorrect contract and do the upgrade internally? Why the do not honour the contract they offered and my wife agreed to? Why vodacom allow 3rd party ******** to contact their clients and sell lies? Why vodacom does nothing to remedy the situation? Why in 6 working days we have not had any feedback from vodacom?

I would like your input vodacom and see if you are willing/able to remedy the current ****-up.
