Can't get sim card activated!

We bought a Vodacom Smart Tab 2 at Game Klerksdorp for my daughter's birthday on 26 July 2018. Game Klerksdorp told us the sim card has been rica'd after that the sim card still has not been rica'd. We went to a Vodacom shop twice and they said that the sim card will be activated and rica'd after 24 Hours. The sim card was still not rica'd. We called the customer care and they also can not help us. We do not stay close to any shops, so it takes us a while to get to town. We can not drive up and down as feul is expensive. We need this matter to be sorted out A.S.A.P. and my daugher is very unhappy because she can't do anything with her tablet. She can't use the sim card.
