This is all too risky now... I've now left Wex (been a user of theirs for over 5 years now), requested my account closed, coins all exited via Peercoin (PPC) with a current 50% loss based on other exchanges...
The number one thing Wex did wrong is to not communicate - and Wex's radio silence for 3 weeks is just appalling. Even if they recover, its just far too risky (imo)...
