Vodacom Upgrade NOT !

Upgrades have gone to the dogs , this is the first time in many years of service with vodacom that when I upgrade I have to continue to pay installments on my old phone for another 5 months . Nobody told me that this will be the case with my next upgrade . What happened to the earlier upgrades ? Is this what we can expect from vodacom now , 24 month down payments on the phone , no early upgrades like I am used to . Really thinking of dropping my contracts with Vodacom and moving to a different provider . And the online upgrade needs work , theres no mention of having installments left on my contract . Had to find that out from the consultant when I went there to pickup the new phone , which I had to cancel because of the installments .
