Sleepwell — premium mattress range, it is all defective

This is regarding a purchase of premium matress (Emporio) that i made 3 years ago by paying 70000, it didn't last for a year, it turned defective and i got a replacement (Emporio). Worst is even the second mattress was defective and we had to again run around for replacement. By which time emporio was stopped and we were forced to pick up comfort cell, though we were apprehensive as it was in the lesser range. We still picked it up with no choice left and now within 6 months that has turned defective as well and it has been since 2 months that i have raised a complaint (108914) and sleepwell is insisting that i pay up for any increase in prices. They are not understanding the basic logic that i am not upgrading or exchanging my mattress for fun but had to go through this coz their mattress are defective and are not durable as promised. I am not ready to pay up anything extra as i have not got a product worth the money i paid yet, hence we are tortured to stick onto the defective mattress still. Is there a solution for this? The area sales manager danesh doe not want to even talk to the customer and help in any way, he shots in his pants if we talk to him about not paying the price, the customer care team is incapable of managing any complaints and we are fed up of contacting them. All i need now is either a replacement or cash refund so that i can go in for better service provider, any help. Is appreciated
