Vodacom unfairly benefiting from the poor.

Each time I buy minutes from Vodacom, I get offers to purchase data that I do not need which I usually accept. This is designed in such a way that you will always accept the purchase even though you do not need. In my view, this is not fair. I cannot imagine how many people are accidentally buying these bundles that they do not need. The last time I tried to claim it I was told that I cannot claim it anymore. I also requested these offers to be removed from my account, but I was informed that it is not possible. Another concern is that the poorest people are the ones who are on prepaid. These are the people who are affected by this problem. Vodacom is not fair on this one.
