What should I do if Suning defaults on design fees?

If you continue to default on the design fee, you can go to court and ask the other party to return the design fee. In this case, before filing a lawsuit in court, you must keep the contract and design drawings signed by both parties as well as relevant evidence, and take these evidence to the court to sue. If the other party does not return the design fee after the court pronounces the verdict, the court will Enforcement. So as long as you have sufficient evidence, go to court and sue.
