Because of a busy weekend I didn't really follow up other than via emails and this still hasn't been resolved. The consistent word from them was that porting a number sometimes takes 24 to 48 hours.. I spoke to a rep by phone today who promised it would be done within 2 to 4 hours.. It wasn't.
You can order your new phone and contract from EE before you receive your PAC code, so long as you give your PAC code to EE as soon as you have it.
