Havells India — Ceiling Fan making noise after 2 months usage

We had purchased 2 Ceiling fans of Havells from Rupam Novelties Juhu on 17/10/23. After initial use the fans started making noise. We complained to the customer care and their service person attended to it on more than 10 occasions but the problem persists. The motor heats up on use and the starts making a noise. Since the fan is under warranty we asked them to replace the same but they are refusing to do so. Please look into.
