This is *****!!!!!

I have set a limit to my account after paying R2,5K the first month, now at the end of August I was debited R3,5K after I have closed off all cellular data and push notifications and only use my phone on my WIFI at work. I do not use my phone at all after hours. I need my money and need answers. Then a call centre agent -Sitadi tell me you need to read the terms and conditions we can charge you and still keep this line open. This goes against all the consumer ACTS in the universe!!! This should stop and Vodacom need to be held accountable for the BAD service and *********** HARD WORKING PEOPLE, THIS IS A FIGHT THEY WILL NOT WIN THATS A PROMISE!!! :( :(
