Vodacom doesn't give information

On the 25th November I received a call say they want to upgrade my contract. She consultant said I would get more data at the same price, however she failed to mention that it's a fixed line LTE contract. I agreed not knowing this. Since I have home internet I'm not interested in a fixed line LTE. I called their customer care and after being redirected a few times I got to the right people. Eventually after a 22 min call I managed to get the router returned. I still have to go through the effort of having my contract reversed.
