The customer service delays the withdrawal, and I have been deceived?

I was recommended by the group teacher to make a deposit and go to SHD for trading. After the teacher made several mistakes, I recently decided to withdraw USD 20,000 to see it. All the teachers and teaching assistants in the group have also disappeared for several days. Other friends on the platform also encountered the problem of delay in withdrawing funds. Am I being deceived? I just want to get my full principal back now, I hope this can help me! [d83d][de1e][d83d][de1e][d83d][de1e]
