Hi renman,
What power company are you with?
I sent the request almost 3 weeks ago, emailed for an update last week and I've still heard nothing back. I'm with Ausnet.
I am with CitiPower. Was in the same situation and I called them up and and played the "I have my builder coming onsite and will be charged a fee if I didn't have the power in time". 4 days later it was installed
