MultiBank Group does not allow to withdraw

In October, I saw the forum said that withdrawal cannot be made from MultiBank Group. I am cautiously ask MultiBank customer service about the situation of withdrawal at that time. The customer service told that there is no problem. Then, I applied for $10000. The results is that domestic banks reject the transfer and the reason is that remittances contains sensitive words and it was transferred from financial company account, but during several consulting with MultiBank customer service about the situation of withdrawal, I have been told that I can only withdraw 1000 USD at one time and there will be a 5% handling charge, and the customer service has been pushed their responsibility, so my appeal now is to ask MultiBank to return me my principal of 150,000 USD.
