poor services

I called on the 5th January to enquire about my data bundles that are disappearing on my contract .The lady on the call centre line transferred me to another colleague of hers to assist me and she didn't instate she said she is cascading my problem to other division and they will call me the following day which was yesterday and until today I haven't receive any call and I cant use my tablet since the problem has not been handled .<br> <br> Since I bought this gadget I don't enjoy it .My data bundles are being depleted like evaporation and when they check if there is any services provide that is charging me .the answer has been that there is no one .<br> <br> <br> This month only I have used it on the first and on top of that I bought 500 data bundle but to my surprise it was gone even though the cellular data was off .<br> <br> I feel this is disgusting and I cannot tolerate it any more .I feel like cancelling this contract .
