Defective furniture

We purchased a piece of furniture from the shop, but it was delivered to us in a defective condition. Despite getting it repaired, the furniture is still not in proper condition and the defect has not been resolved. When we contacted the shopkeeper and requested a proper solution, instead of addressing our genuine concern, he spoke to us in a very rude, disrespectful, and inappropriate manner. His repeated misbehaviour and the way he has handled the matter have caused us considerable mental harassment and distress. We have already given the shopkeeper an opportunity to resolve the issue, but the problem remains unresolved. We expect the shopkeeper to take responsibility for the defective product, provide an appropriate solution, and communicate with us respectfully and professionally.
