Dear Thitaporn,
A pleasant day to you there in Thailand!
Thanks for contacting eBay Customer Service with regard to your account restriction. I understand that you have been unable to complete your listing. My name is April and I appreciate the opportunity to help you today.
Thitaporn, you don't need to worry because your account is not suspended. You are just restricted from selling. In order for us to evaluate your request to continue selling, we need your help. Please answer these questions, and once we receive your reply we'll then review your account within 7-10 business days.
