Eureka Forbes — Nano ro water filter service issue

Hi,

I have brought eureka forbes nano RO and on each year i am renewing the AMC for this product. my water filter not working since April 2020, so i called the customer care to send the technician to resolve the issue.Every time the technician comes, he fixes it and after a while the machine shuts down again. This has been complained about 4 times but the technician could not fix the machine, and despite repeated requests did not even replace the broken tap. It takes some time to change but they don't come anymore.After that there is no response from technician when I try to call the customer care they are telling they have marked this issue as priority and it will be resolved within 24 hours but it was almost 6 month still no one resolved the issue. Even service engineer try to convinced us to buy new water filter. So please help me in getting this issue resolved.

Thanks,
