*****ING DATA

I started using my wifi router yesterday at 2 and all off a sudden automatic updates started downloading. After 700mb of updates I figured out how to switch off wifi updates. I downloaded 3 videos and was at 1.2gig of data. From this morning 7 o clock until 9 o clock my phone still did updates and I'm now at over 3gig off data in less than 24 hours. From 7 till 9 I wasn't even on my phone and used no apps. I phoned Vodacom and had to switch off running apps in the data usage thing now why after buying bundles for 2 years did I not lose 3.5 gig in a couple of hours but with the wifi I did. Vodacom stole my data and I now am left with basically nothing for the month. I switched off all automatic updates how can it still update if it doesn't do that on data bundles. I want my data returned the first 1.2 before I switched wifi updates off I'm fine with but the rest I want back this is theft. I used 2 gig a month being on fb and whatsapp all day how the hell can I loose 3.5gig in less than a day. This is **************** I WANT MY DATA BACK I PAID FOR IT!!!
