I sold used working item without any defects, with all the accessories, in excellent cosmetic condition.
After a week of use buyer claim that it doesn't work properly and required refund/replacement.
Then he opened dispute, issued chargeback. My account was on hold.
Then he returned item that was not only broken and unusable, but also not the original that I sold to him.
Moreover, buyer' card company made reversal payment.
So, I lost a lot of money (including shipping, ridiculous fees) and got item that was broken and not mine at all.
