If all attempts to contact your sponsor fail, you have to remember the most important fact - this is your business. There are many other SFI sources available to obtain the information / help you require eg the Forum, a3a friends, Launchpad, SFI basics and the Training option on your home page.
The most important lesson however to learn from an unresponsive sponsor, is not to fall into the samr trap - be always available for your Team and lead by example.
