Failure to activate mobile data service

I got a mobile router on the 38th of december and my sim card was not active , i then called in on monday to get it activated i was then informed that it will be active on thursday (4th january) . It still isnt active , I called customer care again today to get assistance again to get it active , i spoke to a consultant who said that he cannot activate it and tranferred my call over to sales where i was also told it cannot be activated and got transfered back and forth and have not received any useful assistance ..this is my second router with telkom and have never had such challenges
