Phone not registered on Vodacom Network after 2 days

I was delivered a new phone and a new contract last week. Instead of sending a microsim, they sent through a normal sim.

I called and asked for a microsim which they delivered this past Monday. After spending a few hours on the phone to their call centres and after sales service over the past two days, my phone is still not registered on the network.

Any advice on who I can contact to sort this out would be appreciated.

Vodacom rep - some assistance would be most welcome.
