UPS lost my Fios Return Equipment

Hey Verizon:

I have called, emailed, and called about 10 more times. UPS lost the equipment I sent to return to you, and now UPS refuses to open an investigation becasue they tell me it has to be initiated by Verizon. So of course, I call Verizon (about 10 different times) and am given the run around by every one I speak with. EVENTUALLY I get to speak to a "manager," who informs me not to worry, Verizon won't hold me responsible since UPS lost the equipment. That was last weekend, since then I have received 2 emails and a phone call from Verizon asking me where the equipment is, and that it is due by April 5th. Of course, I reply to those emails, and tell the person over the phoone the situation, and provide them with the tracking number (Which is odd in and of its self, since Verizon supplied me with the shipping label and tracking number themselves), but I get NO HELP.

Help me out here Verizon!!!!!!!!!!
