So beyond the "NO FEES for sellers!" EXCEPT THE NEW FEE to get YOU MONEY OUT OF Mercari that everyone else is complaining about? Their customer service is THE WORST. I kind of think they KNOW this because they won't let you fill out a review for how much they suck UNLESS you are willing to call an issue Resolved. So besides the fact that they don't actually speak English so they never really know what you are saying or complaining about? You are never usually having the whole conversation with one agent so you almost have to start over every time you talk to someone and they NEVER actually help you SOLVE ANY problems.
