Bittrex wallet in maintenance mode?

Has anybody else had any problems with the Bittrex wallet it has been in maintenance mode 3 or 4 days now, I just sent Bittrex a support request and the auto reply said it could be awhile, all we need is for new investors to have their coins frozen on bittrex and then possibly lost.

ya just imagine if the 47% of total supply was lost on bitrexx, that would change things a bit, I never keep my coins on a exchange, to many things can go wrong,
