The question is, if the package does not resurface, what will happen then?
We know it arrived in Memphis, we also know there has been no evidence since of it ever leaving their Memphis hub. If their "final search" turns up nothing, how can they stop searching? If it got on a plane headed elsewhere, with no documentation of such an occurance, isn't the burden of proof on FedEx to prove it's no longer in Memphis?
Because if they can't do that, the only thing we can PROVE is that it entered their Memphis hub, meaning it's either still there (hence, how can they stop searching?) or it was stolen.
Either answer is unacceptable.
Or it was misdelivered without properly being scanned. Or it was destroyed via conveyer system and unable to account for label info ...or the label did come off and an employee didn't properly locate it or register it , or it really is lost or got stuck to another delivered parcel or maybe stolen etc etc. really no way to know
There are a lot of possibilities and without insurance the bottom line is not good news for you. Still hoping it shows up
