What can the customer do to me on upwork if the payment was through a stick?

Question

PayPal

The client wants unreasonable edits, does not want to pay extra. He threatens me that he will complain about upwork. The payment itself was on a direct Cerns stick. On the upwork, I hang at his work in an interview.
Can he odesk scold me?

Answer 1

When paying outside Odessa, you most often get a permanent ban

Answer 2

If he proves that he paid you outside the exchange, then you will be banned. It will be easy for him to do this. It depends on who offered it first.. as a preventive measure, you can complain about him and say that he wanted a discount and forced you to work outside the exchange :)
