Flipkart — Flipkart furniture quality

I placed an order for flipkart 4 door wardrobe and when i received the product i was not allowed to open the product. When the technician arrived i found that the back of the wardrobe was paper thin and was not as mentioned of engineered wood. I'm very dissatisfied by the quality i received and want to return the product.
But thought lets give it chance after at the time of installation techniquen said there is bend in sheet. The door get open even they are locked properly just with slight force it makes noise even when it is not touched.
I had paid Rs.16090 for such cheap product i don't want replacement for this product i want my refund.
