1, employers and workers must participate in social insurance and pay social insurance premiums according to law. If you don't pay, it's illegal.

2, the clothing fee charged by the company is also illegal, and the work clothes should be provided by the company free of charge.

It is also illegal to deduct wages. Performance 1500 is not a salary, but an agreement. If you finish it, the company is obliged to give it to you according to the contract. If you don't finish it, you can't give it.

I suggest you pay attention to collecting evidence and go to the Labor Arbitration Commission for arbitration.
