I realy do HATE Vodafone
I used between 3-5gb the past 3 months
last month once they sent the text saying I was approaching the 500mb limit and if I went over I'd be charged, I went over by about 250mb just to make sure I was over, then all the cancellation letters
I even supplied the proof they wanted to show that I believed my bill would rise by more than 10%

now today I get the bill and the b@stards didnt charge me

what more can I do?

start going over again and again until they do charge me?
