Feb up with Vodacom data costs!!!!

As a "pay as you go" client of Vodacom I am fed up with the cost of data! I hardly get any "special offers" when my data is low. Considering that I spend over a R1000-00 p/m on data alone, you'd think that Vodacom would offer me better rates. I am not interested in a contract for personal reasons, why don't pay as you go clients get better rates for data and contract clients do? The USSD offers on "for your town" are ridiculous as well as the cost of data when buying for 1 day or 7-30 days is expensive. Come on Vodacom, these are hard times.... get it together! Oh and please jack-up your customer service you have enough money to re-train all your employees thanks to all of us.
