Sleepwell — Selling faulty products even after knowing about it

Sleepwell sold me a mattress which is now claimed as a faulty product from their own company executives, it's sold to.me for 43000 rs and it developed issues in 6 months. Gave back lain and back issues to my grandparents who had to sleep on the floor for 2 months because of the fantastic service from sleepwell .in lockdown these guys say that the mattress is not being delivered as the logistics is not working . No one listens to the issue, no one cares . Fraud company, fraud products, gives only excuses.
