Over-priced data not loaded after several attempts, poor service, lost me as a customer

I tried 5 times over the festive season to buy data for my phone with no luck. The exorbitant data costs were added to my account (of course!) and I received confirmation of the transaction and the standard "your data is now active" SMSes but no data was ever loaded. I emailed ********** asking them to refund me and got a response 4 days later to phone another number. No apology or explanation. I rep**** to the email with my frustration and was again fobbed off by the customer care team. Turns out an external company handles these complaints and they have no power or knowledge to handle them. That is not an answer, nor is it a viable system. I am cancelling my Vodacom contract the minute it runs out. I'm tired of paying the highest rates for data and yet not being serviced in any way. Vodacom has lost me as a customer forever. I have been one for over 20 years and my average spend is over R2,000/month. I look forward to no longer contributing to this bloated corporation's revenue, literally counting the days.
