Oh dear, seems like crap customer "service" – an employee with little or no interest in ebay or people wanting to work with it.
Yet, having quick look just now, I see a bilingual – Chinese and English – sign up page at http://pages.ebay.com.hk/eng/registration/index.html
– however, see next post saying the subsequent registration pages are Chinese only
– I was checking using Chrome browser, as maybe could use google translate to get some kind of translation. Maybe don't need to do so, tho, if the bilingual page works.
