How silly it is. I finally decided to recover my oldest ebay account with ID jianshuo.
That was an account created 7 years ago, and suspended 5 years ago. I submitted the online request. As expected, nothing happened – no reply – after few weeks.
Then I gave them a call: +1866-643-2959. It worked very well. They promised to send the activation email to my new email address.
Phone works better than email, always for large companies.
P.S. How embarrassing! A former eBay director still need to call the call center to have account released from a suspension 5 years ago.
