Inadequate information on porting

I am an MTN user trying to port to Telkom. I went to Telkom in N1 City Mall yesterday and the consultant took my proof of address and ID copy. This morning I received an sms with a 6 digit number. Shortly afterwards a Telkom consultant called asking for it and then I got an sms from MTN asking me to confirm the port and I did so.

I expected to get another call to explain what will happen next because I have never ported before. Is everything done on my side? Will my number need reconnection. What will happen? No explanation whatsoever. The worst thing is I'm travelling and I will need my phone so if I'm disconnected I'll be stranded.

I need urgent help. I have called every Telkom number I see on Google and no one can help me. They can't even put me through to the store and I can't go because my bus leaves shortly.
