Sim card not activated

I was contacted about 2 weeks ago, and offered an upgrade on my current telkom mobile contract.<br> It was delivered on Friday, but the sim has as yet not been activated.<br> I have tried phoning the call centre on all the numbers, but the phone just rings.<br> In the interim, it would appear that i have now lost the pin & Puk number of the sim too, and i have noone i can phone to obtain this.<br> <br> Telkom say i need to contact Selldirect. but nobody answers
