I've mentioned this in other threads but I had a very significant holding in ETH (more than enough to buy a car) stuck in limbo for about a week until I emailed them every day about it.

I would say call and be on hold for about a hour (no joke, it was around 70 minutes when I called about a month ago) and talk to them to escalate your case to priority 1. It'll then be resolved in about two weeks.
