Account blocked for a week

Hello, I am posting a message here on the forum. For 2 weeks, they have blocked my Vinted account. It says « account permanently blocked » for the reason they indicated: counterfeit, fraud. And I have never sold anything on Vinted because I am a buyer, I have only bought things, I have never put anything up for sale on their site. I will have to initiate proceedings with their site, this is not normal, they do not respect the law regarding this. What should I do please? Can someone give me some advice please?
