Havells India — Pathetic after sales service

This is to bring to your attention the bad after sales service that i am facing for havells product. All other means of rectifying the issue has been exhausted

About the complaint... My fan is having very much noise and speed is also low. I have been complaining since Apr'23 to get it resolved. After multiple follow ups the machine was changed but this machine is much more noise, speed is also low and fan is shaking. Again I registered the complaint with customer care but since last 03 months no one visited or called regarding the complaint. Some of the complaint reference nos are [protected], [protected], [protected] & [protected].
However inspite of repeated follow ups with technician as well as havells customer care there hasn't been any closure on this despite the product under warranty.
