New sim card not activated

I bought a phone online with vodacom on 6 July, a new contract. I told them i wanna port my number from Cell C to vodacom. Everything was fine and my phone was delivered on 9 July. But my sim card was not activated. On 10 July i called to inform them that my sim card was not activated, they said that it was activated i must just switch off the device and remove the sim card for 5 hours and it will be fine. I did that the whole weekend but it was still not activated. I called again this morning, 13 July and i was told that they will sort it out and call me before 12, it is now after 12 and my sim card is still not activated and no one has called. <br> So upset im gonna return it and stay with Cell C.
