Videocon Industries — damaged product

Address:

530001

I've had a complaint with set top box and had filed a complaint and they replaced it with another and the same problem is occurring and wen I've filed a complaint with customer service they said it will be resolved by the help of technician and technician hasn't arrived even after the 24 hours ..
Feels waste of owning the product when it doesn't provide good service.
Please do look in to the issue and respond. This is not the first time ..
Our organization has 4 set top boxes and the service provided is of poor quality.
