if you don't want to return it, turn a blind eye and contact the platform to apply for after-sales.

if you have cancelled the order and the merchant never gives you a refund, you can contact the merchant. Keep communicating with him. If communication is not helped, you can contact the official customer service. Official customer service will help consumers deal with these problems, and the speed is particularly fast.

you don't need to be anxious and angry in this situation. First, you should negotiate with the merchants. If negotiation fails, you can report to the Consumer Association for mediation. If mediation fails, you can bring a lawsuit to the relevant people's court.
