Vodacom fails to allocate Vodabucks as promised.

In last few weeks Vodacom would send promotional smses encouraging me to buy Just 4U voice bundles of R5 or more in return they promise to reward with 5 Vodabucks per purchase, however that doesn't happen as four of my purchases in last two weeks I wasn't rewarded, especially when I spent on Just 4U R12 voice bundles. I tried to call to lodge complaints, but can't get through to the consultants unless their useless virtual consultant (Tobi) who in five occasions could not assist. I now feel like Vodacom is ******** me,as I buy lots of airtime, spent on Just 4U voice bundles for nothing! I am unlikely to recommend Vodacom to anyone!
