Faber — pathetic customer service

Address:

Ernakulam, Kerala, 682030

I own a 3 burner gas stove from faber. One of the burner is not working and i've been repeatedly calling faber customer centre for the past few days to register issue with my gas stove. It takes ages for someone to pick up the call at the customer centre and each time they promise to address this issue at the earliest, but i'vent received any calls from their technicians yet.
