SDAG trading platform is completely unable to withdraw

Withdrawal on the SDAG trading platform Yingmu showed that the withdrawal was successful and no funds were deposited into the account. No one paid any attention to the customer service, and they did not help me solve the problem at all. Completely ignored. After paying the retrospective audit fee, you are also asked to pay 20% income tax, and on the date after July 25, 111 years after the so-called tax payment, you have been asking the online customer service, and the customer service staff seems to be missing. , no response at all. I have found out that SDAG is a trading platform with a guaranteed FinCEN MSB license in the United States. I can withdraw more than 1,000 USDT before, but why after a few transactions, there is also a little situation. There was a situation where the account could not be received, and the customer service in the exchange did not reply, and even asked them to provide the TXID serial number of the transaction to the receiving wallet to check whether the account was issued normally. The payment details show that the withdrawal was successful, but the money has never been received in my wallet. Is it possible to choose a normal and guaranteed exchange to invest in and still not get the normal return it deserves? Then who can we trust! Shouldn't the money we put in turns to nothing?
