Line not registered on the network

I did an upgrade on the 13th August, a sim swap was done for the new phone. Ever since that moment I am unable to make out-going calls, can't access the internet. On enquirying at the branch was told the network has not completed the process. I am soooo stuck, the old phone can't make calls, the new sim is not yet registered in the network . Sim swap takes 24 hours maximum but in this case it's been more than 48 hours , on the system the new package has been administered, meaning already I am charged on the new rates yet practically I don't have a phone.<br> This is utterly not on and disgusting service MTN. I can't even dial the emergency line or your toll free numbers.<br> I have been keeping up with not having network out of the blue but this is the last straw.
