billing rip-off

On the 28th July 2015, I bought pre-paid airtime worth R100 and 1GB data for R149. I then received smses saying my airtime and data balance is zero. Without going into details on how everything was finished in such a short period, I decided to recharge again with R55 airtime and R149 1GB data on 10/08/2015 evening. <br> <br> I only made two calls from my phone which did not last a minute each. I also did not use much data as the network was slow. This morning my data and airtime balance was a zero.<br> <br> I called 100, 111 and 1187. I went to the internet and the email could not be sent. I tried the chat and was directed to an email. <br> <br> I need to know what kind of **** Vodacom is playing at since there is no assistance from your contact channels. The phone options do not include speaking to a consultant. How can my data and airtime balances vanish like that? I cancelled my contract because I was paying too much money and thought pre-paid would be better but now you turn into *****ing my airtime and data bundles so I keep on recharging unnecessarily. <br> <br> I need answers and need them soon. I also want my money back before changing to another provider
