Hi all - to continue on with this FedEx ground nightmare, I called FedEx this morning and after talking to two incompetent representatives, I finally asked for a manager. The manager told me that the package was actually delivered. That the system took a long time to update and that he can see on his gps system that the driver did in fact deliver the package.
They are going to do an investigation on their end to figure out if it was delivered or not. They will talk to the driver too. I am going to call the warehouse on Monday and the manager assured me, he will call me on Monday to figure it all out.
What a complete mess! Never using FedEx ground in my life again.
