Vodacom and data theft

Vodacom is absolutely ripping clients of. I got a notification on my phone stating that I need to upgrade the software. When I tried it told me there is not enough space on the phone to do this.

I had to clean my phone. Whilst I was deleting almost everything off my phone I receive an sms stating that I have used data to the value of R3000. R 3000 to clean my phone??? How on earth is this possible. I have tried to take this up with Vodacom as this is absolute ludacrous. I refused to the pay this as I was disputing it, and then Vodacom went and disconnected my phone untill I have paid the R 3000. To this day this is still not resolved. How can I use data when deleting images from my phone. Vodacom is seriously ripping its clients of and refuses to take any accountability for their actions nor do they care about their clients. R 3000 's data in a span of 20 minutes?

Vodacom owes me a credit on this. As this is impossible.
