Lying about contract

I upgraded my husband's Vodacom account in October this year. After being hassled by calls constantly to upgrade.<br> All was fine, until today. All of a sudden the contract is now pay as you go. I asked the guy that phoned me, PLEASE keep it on the SAME CONTRACT as what it was. Sure mame, no problem!<br> And now I'm sitting with a useless phone. My husband has been with Vodacom for more than 15 years. This is completely unacceptable!!! Why woul I upgrade a CONTRACT to pay as you go?! <br> Seriously this has to be sorted out!!!!! What if there was an emergency?! What's happened to customer service?????!!!
