Vodacom overcharging for nothing

<p>6 months ago i had a thing with vodacom where i put a soft lock on my phone with a total invoice of R450. I recieved a statement from vodacom for almost R3000.00 and went to complain, they ended up giving me half of the amount credit off my bill over a period of time. in the beginning of january 2017 i upgraded to a iphone 7 deal and started using the new phone at the end of january i recieved a bill for R2952.00. This is impossible as my cellular data is off i have uncapped internet at home and at work and i carry a mobile router with 40gigs with me at all time. if i go to my phone setting at the end of jan it gives you a diagnostic report of how much cellular data i have used and the phone's Cellular data reading is 674mb since i recieved the phone. there is no possible way i could have used so much of anything to come to a bill like this... if vodacom does not give my money back i will be going to the papers and take this public as i have evidence that i could not have been using so much data.</p>
