I have a Autopage contract through Vodacom since May 2000. I used to get 20% cash back in my Discovery credit card. That deal stop at the end of Dec 2012. If I port to Vodacom direct or Cell C or any other company is there a minimum period that you have to be with the new company. Read somewhere you have to stay for at least 3 months when you port. Is that true? I cant afford for clients to battle to get hold of me.
