FedEx lost my package (which was a guaranteed 2 day delivery), NEVER called me back when they said they would, made me wait 6 days before they finally gave me the go ahead to contact the seller for a refund, & I'm pretty sure they lied to me. When I complained about never receiving call backs, the last representative I talked to told me that the notes said that they had tried calling multiple times, but that the number was bad (and read off some completely wrong number); however, every time I called and complained about not getting callbacks, they had me verify my phone number.
Luckily I was able to get this resolved through Amazon (w/ one phone call), which promptly reshipped the items with 1 day delivery.
Anyway, the only reason I'm not livid is because it was a personal package, and not one for a customer. Regardless, while a lost package is understandable (mistakes happen), bad customer service is not.
