inactive data sim card

we upgraded from top-up to uncapped wifi beginning of the year, but since then the sim card has been inactive when I call the faults department they refer me to Telkom sales business when i call Telkom business im referred to Telkom mobile, when I do that I'm told i must go the store when i get there I'm told i must call the faults department, this has been going on for over a month now Telkom is giving me nothing but runarounds, we need internet they debited the fisrt month even though the sim card is inactive. i need a solution.
