I emailed HK yesterday. On the subject line of the email, I wrote: Skilled Worker Immigration Enquiry (File No: XXX, VO: TCY). But they didn't reply at all. It's my second email to HK. Next time, I want to send a letter.
Yes, I used the correct email address. Some friends in this BBS sent five or six emails before they got a reply. So I will keep "harassing" HK until I get an answer
