Damage phone and hard to cla warranty iPhone 4

Im sign with digi plan for the iPhone 4. My phone sudden cannot turn on and i go for the digi center they said they have no stock to change one to one for me and asked me to wait for few weeks. How i going to stop using my phone for 2 weeks , people cant contact me and im losing my money right now. So what should i do to? The Digi center people telling me there few hundred peoples have this kind problem they have to wait for 2 months to claim the warranty? Is that Mac facing iPhone 4 out of stock problem? Seriously i very disappointed by the service.
