Crompton Greaves / Cgglobal.com — Crompton Greaves Energion HS 1.2M OPAL White FAN (Remote Operated)

This refers to purchase of a/m fan on 1st Sept 3021.
I am sorry to inform that this fan has an inherent defect of giving HUMMING SOUND at low speed (at # 1 speed)
I complaint to customer care wide complaint nos &dat as given below:
1. [protected]/01 dt 14/10/2021
2. [protected]/01 dt 08/10/2021
3. [protected]/01 dt 05/10/2021
4. [protected]/02 dt 03/10/2021
The complaint was duly attended everytime and maintenance person visited and inspected the problem and decided to change the fan with new fan 2 times.
However the problem still persists and all the 3 fans are giving the same problem of "HUMMING NOISE" at low speed.
The noise is so annoying that one can't stay / sleep in the room with this fan "ON"
It seems, this product was launched without proper R&D and quality controls. This is to request you to look into this problem and resolve the issue at the earliest
