the company does not respond to emails from at least 2 months ...
Yes, I am. I just received an email from Jing Li yesterday (Thursday, May 2nd). I have no idea why she isn't responding to your emails unless, of course, you are threatening them or giving them an ultimatum.
why do not post the email?
same here, she sent me an e-mail on 5/2 and has always been very good at answering.
