I sent in my device, however late and my trade in went from $650 to $182 supposedly for damages. The phone was not damaged, if Verizon can make those changes and short you $418 dollars then you should have the option to receive the device back or get the new trade in promo credit. If you can take the credit away then you can apply it. Also, not returning a device and changing the value that drastic is just wrong! #fixitverizon
