Welcome to the EMO Community Forums, @xinionx . . . is this the response you received back from LivingAI after you contacted them?
If so, you might want to know the changes in international mailing by many countries due to restrictions on items with lithium ion batteries being mailed (usually by air due to explosion risk). Also, many companies even brick and mortar stores do not accept returns on anything electronic if it has been opened as once it has been used, they are unable to resell it.
We have a place here on the forums you can sell your EMO if you wish. I am sorry to hear you are not happy with EMO but there are others who would be happy to give him a home.
You can check it out here.
