You need to go back and look at the paperwork that you signed when Fed-Ex approved you to ship Live Harmless reptiles, you waved allot of the stuff that normal Fed-Ex customers get..Like if it dies in transit they aren't responsible even if you insure the package. Guaranteed delivery time is another one of those things in the service waver if memory serves. Also they have the right to reject your approved status without notice at any time..Check into that before you go making a bunch of noise..
While I can understand your frustration 20 minutes past 10:30 for a properly packaged animal isn't a big deal..Even a few hours. The time to worry is like when it's stuck in Knoxville with 2 feet of snow on the ground and the delivery time is estimated at 4 days...that's when you start burning up the phone's.. LOL
