Xigen refuses to pay commissions and offers no access to withdrawing money

I have cooperated with the platform since the end of 2018. But it has not paid me the commissions in January. The payment was delayed to 2019. It said it would pay me in March 10, March 20, and April 10 in three batches. But the money remains unpaid so far. Now I contacted the platform but got no reply. It is running away. The related companies are the Sunrise and Hang Lee. If it remain silent, we will go to Beijing to make complaints against it.
