About a year ago I took an SDI course, and I have yet to receive a certification card. A few months after the course, I got some excuses as to why the cert wasn't processed, but the instructor is no longer responding to my emails asking what is going on. Calling isn't really an option as there's a 14 hour time difference. Who should I contact to complain or otherwise get this resolved? I expect I'll have to redo the course at this point.
