Mercari complaint: Deception, withholding funds and shutting down account with misinformation

I have I have had people ask me but first and foremost I want my account restored. Additionally they are withholding almost $2000 of m money and will not allow me to pull it out I got a notice out of the blue this weekend that they discovered I had a previous account which was “ shut down for prohibited conduct therefore they were shut down my count. I did not have a previous account! My sister did..,NOT ME!!! They either fail to respond or respond with what I feel is a “ canned response “ they have deactivated my listings. I have no way to communicate with sellers but most importantly buyers. When I asked for documentation and information that led them to make this determination they cited the previous account was under the user name Kelly both my sister and I are called Kelly depending on whom the person is. Beyond that I can assume the same address but my sister lived with me at one point in time!!!! Last they have almost $2000.00 of my money. It will not allow me to transfer what actively in my account and they will not respond to me at all!!!! First I went online and read reviews. Apparently this is a very wide spread problem with mercari. I literally read hundreds of reviews on different sites where people were or have experienced this. I read many reviews citing people didn’t ever get their money , had to fight for it and if they did get their money the shortest timeframe 21 days!
