EVER SINCE I DID MY UPGRADE MY AIRTIME KEEPS DISAPPEARING. I HAVE A BLACKBERRY 9720 HANDSET WHICH SUPPOSED TO HAVE UNLIMITED BIS YET MY AIRTIME IS BEING USED EVEN IF I DO NOT USE THE PHONE AT ALL. I ALSO KEEP GETTING SMS SAYING I AM USING THE DEVICE OUT OF BUNDLE RATES. WHAT DOES ALL THIS MEAN - I WANT TO KNOW WHERE ALL MY AIRTIME IS GOING IS THE BIS WORKING FINE - PREVIOULSY I HAD THE SAME HANDSET WITH NO PROBLEMS - CANT UNDERSTAND THIS-HOW AM I GOING TO BE COMPENSATED FOR ALL THE MONEY LOST THUS FAR - NEED ANSWERS URGENTLY AS THIS ENQUIRY IS GOING ON FOR OVER A MONTH NOW AND STILL NO FEEDBACK!!!<br> <br> ADDED TO THIS EVERY TIME I QUERY THIS MY OTHER DATA CONTRACT BECOMES SUSPENDED FOR SOME REASON AND I HAVE TO KEEP CALLING THE CALL CENTRE TO RE-ACTIVATE. WHAT IS HAPPENING WITH THE SERVICES AT MTN - IF YOU CANNOT RESOLVE MY MATTER WITH FIVE WORKING DAYS I AM GOING TO RETURN THE DEVICE
