[Resolved]  Elica — Gas stove not working properly

Address:

Mumbai City, Maharashtra, 400067

I purchased a gas stove from Kohinoor electronics if brand Elica. The sales person advised me it is a nice Italy brand.
But since my installation, that is almost 3 months back, the stove is not working properly.
Inspite of registering complain with elica as well as kohinoor, none actions are taken.
Initially a junior technician came from elica, but he couldn't solve my problem. He left saying they will arrange for a Senior technician. But nothing is happening.
Even after speaking to kohinoor electronics regarding the same, they just keep saying that they are working from their end but nothings happening.
