How do I follow up my Application in the Embassy?

I already have my acceptance letter and I got my reference number. It's been a year and a half now.

Do I call them? My current problem is I can no longer access the email I wrote in the form due to a hacker attack.

Send a case specific enquiry, and inform them at the same time of your new email address (which you should already have done)
