Most Pathetic Customer Service Ever!!

During April whilst I was overseas my 3G card got ****** and an amount of nearly R14000.00 worth of DATA was ran up on my account which expired in Dec14 ( which I wasn't even aware of as I haven't used the device since Dec14) . My understanding was that my contract with Cell C was for contract with a cap of 2Gig a month. How the person that stole my device could purchase 20Gig at a time is beyond me...but Cell C just shrugged their shoulders as it is not their problem. I understand my responsibility towards the 2 year contract ( which has expired) and as such made payment arrangements to pay off the amount abused on the account. Despite this , Cell C still deducts the whole balance of my bank account . Can someone please just call me to finalise this as I hold on since 08h35 this morning till 09h05 without being able to speak to the right person as I am transferred from person to person. Cell C your service is really pathetic as I cant believe that one cant resolve this matter . You are so quick to take your customers money yet so pathetic in your service delivery.
