NO BIS SERVICE

Load BIS on Sunday, 27 September 2015. Since Monday NOOO BIS. Called the customer service department on Monday to report. Was told that the BB serves was off and that the technicians are working on the problem and that they would lock a call (email) and that I will receive a confirmation email> received nothing on Monday. Tuesday morning another email was logged to the technicians and I again was promised a confirmation sms. No sms received. Tuesday evening I called 082111 again and only then did I received a confirmation SMS. I called them again today at 12:15 and was told that the BB server is on again and that BIS is working and that I have to take out the sim and battery and leave it out for 5 min and after the 5 min BIS will be working as my account was deactivated and she has now activated it again. Done all that just to find that there is still NO BIS!!! called them again and was told a diff story again. WHAT IS GOING ON WITH BB BIS??? I have paid for the service but cant use it!!! Also cant speak to a technician to get a true version as to why BIS is off!!! WHAT IS GOING TO HAPPEN TO THE DAYS PAID FOR BUT DIDNT USED???
