Eureka Forbes — Water purifier not dispensing water

Dr.Aquaguard water puriffier of eureka forbes is made in such way that it stop dispensing water after 55 hours controlled by chip. It is ok but. Company after sales services is so poor that no body attending the complaint even after lapse of 48 hours person attending call advise that company remain closed for 5 days for diwali vacation.
Automatic complaint registration working but thereafter no resposible person following up today the company start work but not attending complaint giving govt.Covid guidlines.This is the position of tata companies .Very very poor services.People take the product on the name of tata but after sales services is full zero.
I request to attend my complaint number [protected] urgently.
