Dissapperance of Data Bundles and Airtime

Morning<br> <br> I am a Vodacom customer with 2 contract phones, to my suprise even though I am offline my Data Bundles and Airtime its being used and get fished and when I make followups with Vodacom their Explanation is Nul and Void because they always tell me about my cellphones systems which are taking my airtime but my cellphones sytems are always offline. This thing of dissapearance of Airtimes and MBs is irritating and is on my nerve now and I even decided to cancel everything with them but to my suprise their cancellation fees is equivalent to the amount which I must pay for the remaininmg months of the contract. Is this really possible? I am sick and tired about **** Airtimes and MBs of this Network. I want to see it out of my face. Can someone help me please because All Vodacom consultant I contated they are not helping me with anything, They are just singing the same song to me which is not helpful.<br> <br> Regards<br> Sepotlo Moremi<br> ***
