Tracking number

I ordered something online. Last week I got a email saying it had shipped and they gave me a tracking number. Today I went to look at the email to get the tracking number. When I tracked my package it said it was processed to ship and was still sitting in the warehouse. What is driving me crazy is that they said it shipped when it is actually still sitting in the warehouse. They said 3 to 7 business days and it has already been 4 days and it is still sitting in the warehouse. I have no idea when it is going to get here. If I get a rate this order email I will be saying I am not happy with the speed of delivery.
