Data been ****** from us all by Mtn

Mtn has been cutting my data,eg say I load a gig ,even before its 3/4 used up Mtn cuts me off and when i do complain they come back with the ridiculous answer of it my handset and back ground apps , after I have explained that my phone has been set up not to allow any background data use and any app wanting to go on line will request it . If you aare unfortunate to be with Mtn ,watch how ur data is been "used" and you too will see that you are been ****** by Mtn They obviously think we are idiots and will not notice that we are been ****** blind ,firstly by the price we pay for data and than we still dont get for what we pay for
