Incorrectly billed for out of bundle data charges!!!

<p>Today I decided to long onto My Vodacom and check my bill. To my surprise my bill is R3785 of which is normally R1100! ***! According to the customer care this is for out of bundle data usage! How is this even possible when I am on wifi the entire day and still purchase 3Gigs of data monthly. I am in utter shock! To make matters worse I am not able to view my invoice online! I was told I will be contacted in about 16 working days...but by then its too late to adjust the account. I have been with Vodacom for many years and have never paid a bill this high. This is ridiculous! Should I not have this resloved I will be forced to take this up legally! VODACOM get your act together! </p>
