Vodacom discriminatory pricing

This company loves to milk their customers for everything they are worth. A few months ago I noticed that the data deal that I used to purchase disappeared from the VodaPay store page. I was frustrated, but didn't think much of it until a friend of mine mentioned that he was getting an even better deal. I compared the deals that he was offered to what I was offered. He was getting substantially better deals than me (essentially getting data for R20/gb) while my best offer was Around R80/gb). I have checked on other friends and familie's phones and I have noticed that those on contract seem to get substantially worse deals. I guess they know we are locked in and see it as they can do whatever they want, whereas they need to continuously prove themselves to the non contract clients. What a way to show loyalty.

So essentially if you are on a contract you pay at least 4 x more for data, I am stuck for another 2 years and I am regretting renewing my contract. I am looking forward to the day that they call me to do my next upgrade (although then I seem them attempting to come to the party when they realise they are going to lose my contract)

VODACOM to be clear I am passed the point where you can rectify this. Please do not contact me, this is for the sole purpose of raising awareness of your ****my business practices.
