Disappointed

I recently moved to telkom mobile from MTN after years of terrible service and signal, I got my contract right after the Summer of Wow promotion, when getting my phone I asked the sales rep if there won't be a new type of special coming out soon where extra data is involved, she said no unfortunately not , now I see my contract comes with an extra 24 gigs of data !!! I spend so much money on extra data bundles a month, which is a mission to get might I add, and now I see that I could have gotten an extra 24 gigs of data, I feel horribly saddened, disappointed and wish that this could be rectified ... in any way .... I am so bummed out by this especially because everything up till now has been great with telkom mobile
