Faber — hob 604 ci ignition problem since installation

Address:

New Delhi, Delhi, 110087

Ignition part of small burner faber hob model 604 ci installed on 22/10/2016 by faber service provider one touch solutions services, paschim vihar, new delhi is not working from the very first day.
Every time their technician visit to repair says that it will be replaced within 2 or 3 days but they never repaired or replaced that part.
I never expect such type of after sale service from a company like faber.
Needless to mention that i will never purchase any faber product and never recommend to anyone for purchase of faber product
