Complaint on MAX ,which gives no access to withdrawal

I invested $5,000 in the MAX platform on October 2017 and made a loss of $1,100 during the actual operation. In February this year, due to family needs, I planned to withdraw a portion of the fund from the platform, but found that the customer interfaceof MAS MS has been unable to log in.The application for withdrawal has also been delayed. I was told to wait patiently since the system was in upgrade.Later,customer service didn’t reply to me and hung up when I inquired about the withdrawal.And the agent who helped me deposit money was out of contact.Hope traders pay attention to the platform.
