Eureka Forbes — Service request and complaints not addressed

I had raised a service request on 21st Aug regarding non-functional water purifier against my AMC.
Subsequently I have raised 5 complaints / escalations from their mobile app and phone and the service request / complaint / escalation is yet to be addressed. Every time I call the customer care team, they tell me complaint or escalation is registered and yet no one calls or visits to address the issue
It has been more than 15 days since the service request was raised and its really frustrating that the company is least bothered about the service request and complaints.
This is unacceptable and request you to please help
