Vodacom Sells things that don’t exist

I was called by the Vodacom rewards department and offered an upgrade on my data line and was advised that I can now transfer data from this contract to my cellphone contract Whenever I want. I advised her that I needed this as my cellphone does not have enough data and I always end up buying more every month. I therefore opted to upgrade my data contract as long as I can transfer data between my 2 contracts whenever I want.

Guess what, nobody in Vodacom knows about the ability to transfer data between contracts whenever one wants. I have tried numerous times, but nobody can cancel this data contract, I am continued to be transferred to department upon department.

I have never expected this from Vodacom, never expected them to sell me something that does not exist nor did I expect no service after the sale of the contract.
