Sorry for your situation. Since you are located in the Ukraine, there may be several reasons for your restriction. You have several Non receipts from customers. Your listings are private, not good. There still may be a restriction in your country due to the conflict with your country and Russia. The one that rings most clearly is your customers are not receiving their items. That can be the kiss of death as a seller. More than a few Bad Buyer experiences will result in not only a restriction, a permanent suspension. My suggestion is to reach out on social media via FB:

Good luck to you!
