Changing price plan without consulting customers

I'm so happy that my contracts is expiring this year I wanted to upgrade but with vodacom that have the power to increase prices and change contracts how they feel made me change my mind there is alot of other companies out there. If vodacom had we as clients best interest in mind they would have wait respectively till there clients upgrade and inform them that there current packages does exist any more or take the punch to inform there clients that the packages have change but they will still pay the same amount but have the increase of benefits. This is the second time that vodacom have decided to change packages without consulting customers and this will be my last because they have lost me as a client.
