MTN ****ty provider

Listen i am so tyred of MTN and their bull**** storys as to why they take 2.5 and upwards data per day on ny phone i was at Cell C same settings on my phone, and i used only 15gig data a month!!!!! Mtn has got loads of flipping BS storys. Im only using this fcup provider deu to my Cell C sim that got damaged. Im so tired of loading 1.5 gigs every fcing 2 to 4 hours. And consultants bsing me that my settings and apps shoukd be disabled. Why is that not necessary for Cell C?????!!
