eureka forbs — Water purifier not functioning

Address:	556 b/2 Tapkeswar colony Garhi Cantt Dehradun
Website:	Eurekaforbs

My water purifier AG Nova is non functional since 05/07/2021. We are forced to drink unfiltered water. The company is not living up to any level of satisfaction.
One untrained technician came in the FN on 10/07/2021 & told me that one part is required & he will have to go to get it. He promised he will return by 5.30 PM on 10/07/2021.He has not turned up so far. He is not picking up phone.
We are really fed-up with the company.
Please suggest if I have to go for some legal action
