Unable to get hold of anyone

I recently swapped over from contract to prepaid. Settings was sent to my Samsung which I have now replaced with a Blackberry Z10. I am trying to get hold of the CC for weeks now, but each time I either get disconnected or get told by a automatic voice message, that the CC is busy and cuts me off. <br> <br> I need to know how to get these settings sent to my BBz10. i checked the MTN web, but nothing. I tried all the * numbers, but nothing. <br> <br> I need to speak to a CC agent, but I can never get hold of anyone. This is putrid service.<br> <br> Regards<br> Noer
