Kurl-On — Product size is different than given in the tag, Back pain, Mattress cushion compressed as soon as we even sit one side bending

I purchased Kurl-on Pocket Spring Mattress (Variety: Angelica Box Top) (Product reference code: AE/ 78X72X6) which has come with 2 inch additional cushion (No idea why the cushion size given is 2 inches more than what is there in the description of the tag attached on the product).

I purchased it (around 34, 000/-) and the quality is getting worst day by day. The additional 2 inch cushion provided is a biggest failure as per my usage the quality not good even if you sit on the mattress its compressing and the action is all over the mattress due to which uncomfortable sleep and back pain started for my parents. We stopped using it as soon as we identify the flaw due to which its causing back pain issues.

The product I purchased is expected to be premium quality depending on the value I paid. However, the quality is not up to the mark. Could be manufacturing issue or the product description given on the tag and actual size is different. Since it is causing health issues no body would like to use it and get their condition worst by paying so much. Hence, requesting to get the refund to me or replace a good value for money product as per the description given to the tag. To compare the cushion on this mattress is as good as Kurl-on mattress which we will get it for 15K.

I have purchased the product from Home Town (Hyderabad) and attached the invoice along with product description tag given on the mattress which is not the actual size of the product manufactured.
