Ouch! You couldn't use any of the services to find your phone? Usually they can ring your phone even if it's on silent. At least you know it's in your house! I once hung my hearing aid on the chandelier while on the phone. Completely forgot where I placed it and took at least a week to find it. Might've been longer since my parents and I were starting talks of buying a new one before I happened to look up at dinner. All that to say, it will turn up! Don't lose hope!
