Vodacom a bunch of ******!

I am at the point where I can no longer tolerate Vodacom, I just wante everybody to know how terrible the network and customer care service is before you decide to sign up a contract with Vodacom. 6 months ago I complained about the network and after a few pointless emails nothing was done to resolve or assist with the issue. I am never able to connect both on my phone and my mobile wifi, but yet 2 gb of data is gone within 8 hours. IMAGINE YOU LOAD 1 GB OF DATA, NOT ABLE TO OPEN ANYTHING, FACEBOOK, EMAILS AND GOOGLE BUT YET 4 HOURS LATER A GB IS GONE FROM MY MOBILE WIFI! Can someone explain this to me because to me it sounds like *****ing!!! I loaded 2 GB this morning at 10 at 5 this evening it is gone, data usage shows it was used by Google which I never even opened today??? Oh and don't even bother calling the call centre because I spent the last half an hour WAITING to speak to a consultant.
