Nilkamal — Installation of a delivered product

Website:

www.nilkmal.in

Ordered product got delivered. But not yet installed. It has been weeks. no one is responding and everyday technician calling claiming they will come today. But no one is showing up. Regarding the installation spoke with almost all employees of Nilkamal from all parts of india- Bangalore, chennai, trivandrum etc
Everyone shares a different number and asks to call team leader/ shop owner/ coordinator/ technical head etc.

The funny part is they are not willing to take the return as well
