Im struggling to get my new sim activated

I've been a Telkom mobile client for over two years and I recently went for an upgrade, On the 06/02/2016 to be specific. I was assisted by Thandi who advised that I needed a new sim card because my new device didn't allow for a normal one that I had been using. She confirmed that the new sim had been activated before I left the store, the biggest mistake I did was not to confirm what she said until when I got home, I assumed that it might take a day or two to be active but still after those days it didn't work. I contacted a customer care and was told that I had to go to a store that's the only place that does the activation. Following Saturday which was the 13th i went there only to find that they were offline. I was assisted by a guy named Edgar who assured me that it wasnt a big deal, he will activate my number once their system was up and running, he even gave me another sim just in case the one i had was giving him problems. Following day (Sunday) still my new sim was not working and on Monday. I tried calling the store but the was no answer from 9 in the morning until 5, i wanted to check if the systems were working or not. Until today it's not activated.
