Royaloak Furniture — Received damaged Recliner

I have ordered and purchased a Lara recliner from the kukatplally store on[protected] and received the product on[protected].
The person who delivered the product he said for installation executive will come and he will do the installation so on[protected] executive came and did the installation so when he opened the box and installed i noticed there were few stitches are not proper and it was tiered off and also noise was coming when i seat on recliner.
so he said i will inform the issue and service executive person will come and he will have a look.
on[protected] service executive person came he did stitches where ever required and for noise he opened the recliner and started replacing the parts screws and rods with old parts which he brought in his bag and started opening the chair hitting with hammer on it, when i asked why you are replacing with old parts which are color fade-out parts he said company provide these only when repair comes.now after replacing the parts the recliner is not opening properly making more noise when i seats on it and locking is not happening when i stretched the legs parts and push back the seat, ts not staying it keep on pushing me front locking is not happening and making more noise when its swings.
i dint expect that royalock provide the solution with replacing with the old parts and not even the service executive is listening he is convincing me that you have warranty use it now if any issue come will repair.
my question is why to adjust with damaged product i have brought a new product not a second hand product with having issues on it.
i tried to tell the same thing to customer case so they are saying we will do the repair the issue i dont want repair on new chair when it comes to new means there should not be any issue or damage on product then only will call it as brand new not with issues.
please replace this chair with brand new chair not with replacing parts to it.i purchased a new not used one to repair.
i would be gland if you can please help me on this and resolve my issue.
