poor service

Its been 3 days since i bought BIS for my phone but i cant use it as apparently vodacom is having a problem with loading it and always when i call i'm told they are aware and their technicians are busy fixing the problem it will be sorted in 24hours but it has been 72hours already. How are we supposed to access other apps that only use BIS as they know blackberry not all of the apps use data and even so are they going to extend the expiry date with the days we cannot use the BIS
