Before purchasing S22 I documented every topic, my questions, and E Com's answers. When they would do it, I got the agent to email me what they had just told me so I wouldn't have to rely on a number (ticket#) to show what they said. Kept all email correspondence. Ifo on trade in said to use the box it came in, no mention of old phone box. But I reused a box I had, documented all that including the FedEx pick up.
They go it, no problem. Only thing is they tried to ding me on it's value. But a miracle happened and 1 quick call reversed the chargeback.
Glad to be done with my 3+ month process of getting the phone and seeing everything through..whew !
If I had the og device box I would have let them have it since I wouldn't have a need for it. But not the new device's box to send the old device. The new box is part of the new purchase.
