I purchased a new iphone 12 in December with a trade in promotion of $580. I did not receive a return mailer in a timely manner so I contacted Verizon and they sent me a mailer and gave me a submission ID. I mailed the trade in and got receipt confirmation. When I checked the status of the trade-in, it stated a value of $52 which would be credited to my account. I contacted Verizon by phone and was assured that I would receive a $24.17 credit/mo for 24 months. I checked my upcoming bill and the credit was indeed present. When I checked my upcoming bill again a few days later, the credit disappeared. Between online chats and phone conversations I have spent in excess of 4 hours trying to resolve this issue. I think that the person that sent me the mailer gave me a new submission ID not associated with the original promotion so it looks like it was a regular trade-in. Once my current phones have been paid off, I will be switching providers.
