Sleepwell — issue with the mattress

Address: 110009

I bought sleepwell’s spintech air luxury mattress, which costs above 30k, in 2018 nov.
I think the company’s mattress life is 12 months only and they start to wear & tear after that. If you lift the mattress even for 10 minutes it will not come back to its original shape. Their customer care nos are always busy and their executives are super busy as they will come to attend you after 2-3 days.
What stuff is the company selling, i fail to understand. This is the second time i am facing the same problem, first time they replaced the mattress now i dont know what they are going to do because the problem persists in all the luxury matresses that sleepwell is selling.
