Vodacom horrible service

Good day

I am so disgusted with the horrible service that I receive from Vodacom. I have received a bill of R3300 for out of bundle data usage for a rooter that have not been used for the past 4 months the worst part is that this is the second time that this has happened. If I could cancel all my contract with them with immediate effect that is what I will do.

If I go on my Vodacom app it states that there is still 2gig data left. Very confused.
