vodacom *****ing data and airtime for nothing!

I recharged with 2GB data yesterday morning.it less than 10minutes it was all gone.i had no apps running or updating in the background and also was not using my phone.all apps set to update only over wi-fi despite speaking to a consultant more than once yesterday it has not been rectified or refunded I then recharged with R50,in less than a minute it was also gone after then speaking to a consultant again, I then demanded to escalate the matter and speak to a manager, after making me wait for more than 10 minutes, finally someone else came on to the line.he then said i need to send a screenshot of my data usage on my vodacom app. app usage reflects only 800mg used in the last week .he promised to get back to me and either refund my money or data and airtime after sending him the screenshot.it is now a day later and i have not recieved any response,feedback or refund! the level of customer service is quite shocking! in essence all vodacom is doing is *****ing peoples money
