Havells India — Local Technician not responding Calls

I raised a Complaint for my newly installed Ceiling Fan which was generating Noices and was running at Unequal Speeds.

The Local Technicians are managed by Company named Subbalakshmi Agnecy whom will assign the Technician.

The Technician is not at all picking up the Calls and its been 4 Days of Complaint being Raised and less than a Month of Purchasing the Product.
