Eureka Forbes — service complaint, rude service staff

I had purchased eureka forbes 8l aquaguard cd genius ro+uv+uf almost two year back. Suddenly, it stop to work and totally turns off. Service representative came and analysed the product and informed that its pcb circuit needed to be replaced. It has been several days and nobody is having an answer for the availability of pcb circuits. Also here i attach some picture he left the ro machine totally open after he checked the fault, is it a right way to treat or servicing your product? When we tried to talk to the service representative he answered very rudely and said he is very busy. Also the pcb circuit has not arrived yet every time he just says tomorrow, definitely he will come and fix it and cut the phone quickly. He has never come from the last 5 days. My family has suffered without the purified waters for the past several days.

If i do not get proper answers and service on priority basis then i am going to the consumer forum.in addition, i will share all these information on all the networking websites so others don't suffer like me and my family.
