Big liar, can't withdraw money at all

I have some friends who have been in contact through stock trading before. In isay365, a teacher led stock trading and later said that the stock market is not good. Let's trade in gold together, and the yield is very high. I will try it too. I played for a few days and wanted to withdraw my principal. The customer service refused to withdraw cash for various reasons. Then let me pay taxes. What's more interesting is that the tax bureau is labeled as the Water Affairs Bureau. This is totally a liar.
