God, I can't calm down. I sent them some bitcoin not long ago. When I quit, the bitcoin in the fog disappeared, but did not reach any address! I still have dozens of coins that need this hybrid service. I need to clean up in a short time to get fluidity. The first time a small amount of bitcoin returned to the fog, I successfully took out my coin, and when I made another second remittance (not too much, about tens of thousands of dollars), the same thing happened! Bitcoin has disappeared from the fog! I haven't reached any of my wallets yet, the transaction didn't happen, there is no record in the blockchain, I gave this feedback to the administrator, I think it will solve my problem soon, just like the first time, but no, I have feedback many times and have not got any answers. This makes me very anxious. I want to ask if this happens often? Or what has been indicated?
