Data usage dispute

I had loaded 50 gigs (monthly data) which now I'm left with 23 gigs I called the customer care, I was told that I should take my sim card and phone to vodacom shop for assistance, I have network people in my area which I was told an Sr will be logged for it but when it came to my data I was told to go to the vodacom shop, why was the same understanding method used when I disputed the data usage.

I spoke to bugle and Kevin and both of them was unwilling to assist. Please contact me on : ***
