Pepperfry.com - Manufacturing defective item not exchanged or refunded

I ordered a wooden bench from pepperfry.com online after checking the item in their studio. The bench was delivered with several manufacturing defects. The back of the bench was crooked. The height on the right side was ** cm while the left side was ** cm, apart from this the base of the bench also was crooked. The right side of the bench was damaged and a bad patch up work was done. Also, spindles shown in the image on their website were ** which gave a good look to the bench, I received the bench with only ** spindles which made the already crooked back long and narrow which completely spoiled the look. The base was dark colour in the picture and the studio when I personally saw the bench and I was given a light coloured base bench. There are holes in the wood and cracks in some places. All these constitute manufacturing defects. The bench was of very low quality compared to what they showed us in the studio and what is displayed on the website. I asked for a refund or replacement and they have refused to say the item is just as is on the website, which is not true. The item is nowhere close to what has been shown to us in the store or the website. I believe I deserve a refund or replacement. They advertise that returns are easy and they are very rude when we ask for a return.
