The official website is closed, so payment cannot be made. The funds approved by the application have not been received

I traded hsi on mt4 software in September 2018 on the platform of zundi international financial group.During this period, a total of $30,000 was put in.However, the customer service suddenly informed the channel maintenance on October 11 and asked me to pay. I have applied for a total of 27,614 dollars.But on October 12, the official website, the transaction link cannot open.During this period, I contacted the customer service staff for several times to urge for payment, and began to reply for maintenance. Finally, I said that I would report my situation to the superior department.After November 16, I contacted customer service and did not reply.I will please pay back my money!
