It seems transaction problems have been going on for a while with them, the OP saying it took 30 days for a deposit to show up. WTF??? haha Yeah forget that exchange, man. You'll have to take the loss and move on to something better. U.S. exchanges seem to be getting their act together. Poloniex, I didn't like in the past because their servers couldn't handle the users and I lost money, but they upgraded since then (that was like a year or so ago) and it's been smooth sailing ever since. Plus, they are getting ready to embrace U.S. regulatory measures so it's safer than an exchange like Cryptopia, but they are also still only trading coin to coin and operate out of Delaware where there are laxed regulations, so we'll see where they go from here.

Losing coins sucks though, hope things get better for you this year!
