OnePlus trade in is an absolute scam.I've been loyal since the 8 proSigned up for the early bird trade in deal for the op13 and was gonna trade my op12 .op 12 was valued at 420 euros which is around £360. Op12 was in immaculate condition always in a leather wallet case and is barely a year old without a mark on it.no screen burn and battery still at 96% .they downgrade it and offer me the equivalent of £260 because it's (showing signs of use) such a vague term to use.i tried countless times contacting both parties and only received cooperation and generic messages with know info with regards to how they graded it.there was no mention of grading when I ordered op 13.now I'm on my own and have to pay €27 to get my phone back.which I'm concerned about because other reviews say that this is a nightmare.so I'm out of pocket ,pissed off and hate OnePlus now.
