Hi,
Does your support working on the tickets?
I have a 3 weeks issue with Sierra withdraw, 2 tickets opened.
You replied to the tickets until you realized that you did not updated the wallet and you sent my coins on the wrong chain.
You, as exchange, must stay in close contact with the developers of the coins in order to avoid situations like this.

HELLO, IT'S NOT DONE. I DID NOT RECEIVED THE COINS. MOST PROBABLY YOU DID NOT UPDATED YOUR WALLET. THEY CHANGED COLLATERAL 2-3 WEEKS AGO. THE TX ID IS NOT FOUND ON THEIR EXPLORER. CONTACT THEIR DEVELOPER. HE TRIED TO REACH YOU WITHOUT SUCCESS.
