Eureka Forbes — Dr Magna RO+UV water purifier

I have Dr Magna RO+UV water purifier . The purifier has always been under AMC. Presently it is under 2 year AMC. Earlier, I was posted in Varanasi where service was satisfactory. Recently, I was transferred to Saran, Bihar near Patna, were the service is not at all available. Knowing my transferrable job, I had specifically asked weather the AMC services would be available at other locations and I was assured all India service.
My water purifier stopped working on 27/10/20. I logged first complaint on 28/10/20 and since then numerous complaints have been logged by me. However, the only response I received was that the complaint is being escalated. 20 days have passed and the water purifier has not been attended. I even demanded refund of AMC amount if the service can ne be provided as promised, but they didnt respond to that either.
