Eureka Forbes — Water purifier worst product

We have purchased this place product about 5 months ago and this is the high end model that we chose. Water stopped coming and the machine wasn’t working from 2.5 months. I have been following up with customer care and raised a complaint on april 8th, he cus care ppl always promised the technician would come in 2 hrs who dint turn up from 2.5 months. I’d like to return this machine and have my refund. Your customer care service sucks big time. If you do not refund i’m going to sue your company i have all the necessary documents.
