Bad Service

I phoned the call centre to find out if I can go for an early upgrade. The lady at the call centre told me I can upgrade I just need to go to the nearest Vodacom with my ID. I could also upgrade over the phone. I went to the Vodacom in Centurion mall where they told me I can only upgrade in January 2016. They said that the lady at the customer care **** to me. I phoned the upgrade nr that I got from the Vodacom shop where they told me the customer care is not allowed to give me upgrade info. And all they said was sorry for the inconvenience. I will wait till January and not renew my contract with Vodacom.
