*****ing from clients!!!

Vodacom debited me R4448 today. I weny into the store and they tell me it is my tablet that used all the data. I did a *111# and it stated that i have 2gig available till end of August and 2Gig available till end of September on the tablet. <br> <br> I have uncapped adsl at home and work so how the **** did i use all that data ? <br> <br> Vodacom said they cannot give me a detailed url breakdown of the data usage either so how the **** can you charge me for data i did not use nor can you prove usage to me ? <br> <br> I will reverse this debit ordrr and i will pay you what i pay monthly and if you even try and list me without proving usag to me i will sue you
