How come my transaction still not complete. The direction was the same...from hitbtc to coss.io. The support team also not replying. Ive got reply from hitbtc immediately but not from coss. Now im really worried. The address that i send bitcoins to is empty. I checked on blockexplorer. It was filled by that amount i send, but afterwards (30 minutes after)was emptied. The transaction history in my newly created account has no records of any transaction. Does anyone have any idea what is going on?

EDIT: sorry mine was BTC not COSS.
