I ordered a ring for my mom which had a guaranteed of two days.
On Friday my package was shipped to Mosinee Fed Ex warehouse which is 1 hour from my house. On Monday my package was loaded on the truck at 7:40 am and was informed by an email it would be delivered by 8:00 pm.
I checked my status on email and the delivery truck was back in Mosinee at 7:04pm and my package was still on the truck.
On Tuesday I contacted FED EX 5 times and they guarented me that my packaged was again loaded and would be delivered but guess what the same thing happened again.
I could come and pick up my package at Christmas morning. Like I had time to do that.
