I hope your issue should be resolved soon by the Betfury because a relatively new casino cannot afford such accusation against them. Also you can show the screenshot of your pending withdrawal of 350,000 tron so we also know that what you are saying is also right. 
Gone from my account.
Now my account can't click notifications and check withdrawal history. Only deposit history.
It will be better if you can share the image of what you are seeing and so that it will clarify what as well you are saying is correct and also will help Betfury team to resolve your issue quickly. The team here seems to respond and taking cares of all the query so yours should also be resolved soon if it is genuine case.
