This is fucking insane. It seems like other people having the same problem. I remember another service which is freewallet.org which is another proved scam. It seems like HTX actually following the same pattern seeing nobody could do anything to freewallet. All we can do is, write and scream but they already spread their name on the internet and people are falling for their scam.
I found myself in a similar situation. HTX/Huobi blocked the withdrawal of funds and is asking for data that I do not have. In response to all my attempts to clarify the situation, they send me a letter with similar demands. The transfer they had questions about was $250, but they blocked all assets in the account.
