I recently traded in two iphone 11's for the iphone 13 promo. I upgraded online and received both new phone in one shipping box. The box also only contained one return envelope. I assumed they wanted both phones together since they only sent one return envelope. I sent both phone back in the one envelope and they only processed one. I video taped myself putting both phones together in one envelope and sealing it.
Ive reached out the CS and they keep telling me they only received one. I can see here that this is a very common problem and it almost seems like they either do this purposely or their returns team is stealing and reselling the extra phones due to a loophole.
Im beyond frustrated as Ive been a great customer for over a decade.
