Awful experience. Never again. I would give them a zero if I could. I bought a phone from a seller there and after 4 days it still hadn't shipped. I contacted Mercari and they said I can cancel it. So i did that and then immediately the seller created a shipping tracking number that voided my cancellation but 2 days later and he still has not shipped it. It's just a shipping order. I talked to Maybelin a supervisor at customer support in Mercari and she said I need to wait 16 days and if he still hasn't shipped they will cancel the order. 16 days ! They refuse to contact the seller and tell him to cancel even though he is not shipping. Worst experience buying online. A bunch of scammer sellers and Mercari. Never again.
