I have seen 'trade-in devices being lost' related posts in this discussion board. I've talked to several agents over chat and phone in the past couple months regarding my trade-in phone that I sent in February which is worth $200.
As per the instructions, I reset my phone and sent the package back with the shipping label sent by Verizon. None of the agents I talked to were able to help me. Instead, they are blaming UPS and asking me to submit a claim, which I clearly cannot do because the shipment label was created by Verizon (sender and recipient).
The agent who I was talking to for over an hour hang up on me when I asked her (politely) to connect me with someone who could help me with this issue.
Clearly, someone at the warehouse stealing the phones at the expense of customers' time and money. Such a hassle. I will never trade in with Verizon again. Others don't do this mistake as well, if you don't want to lose time and money.
