if you get on there they have a ticket system to pelt them with the demand to be able to withdraw and deposit coins to their exchange, and they use I think the same user name (btc38.com) on skype so you can search and talk to them there
**Edit**
add to that live:btc38com as another contact that says it is online support, and shows as a location "china" so maybe that can get us some things moving.
Be careful of this Skype user...
live:btc38com is not from BTC38 support. Yesterday this user was trying to send me a virus file..
the file name (including all the spaces) is '
info btc.pdf __.scr '
If anyone else gets sent this don't open it. Here is the Virustotal scan

is it possible that it is so new that no one knows it is a virus, and what does it do? going to check what you have listed,
