Who I have the same questioned this topic

Warning to Verizon Customers. I recently participated in a promotional offer where you would receive $800 promotional value when trading in an eligible Samsung device. After the store printed me shipping labels I sent the eligible old device in (Galaxy S9). After recieving the device, verizon now states they received an old S5, which supposedly has the same IMEI number as the Galaxy S9 I sent them. They therefore will not provide the $800 trade in value. When searching the IMEI number I was able to confirm it belonged to the S9. I provided proof to customer service that the correct device was sent to no avail. I have had this looked into twice.  Unless they heavily overhaul their trade in system I recommend customers do NOT take part in promotional trade ins.
