I sent my old phone to Verizon as a trade-in a couple of weeks ago, but never received a confirmation email with a "Submission ID" for me to track the status of the trade-in. UPS tracking confirms that my old phone was delivered to the Verizon warehouse on January 13th, but 2 weeks later I'm still getting calls and emails to send in my device.
What do I need to do in order to get this situation resolved and avoid having to pay the cost of my old device?
