Query: Bad customer service

I received the item and notice a sharp notch at the edge of the board (damage). I notified the seller of that and requested for return. The seller wanted me to describe the damage at first and then again asked me to send a photo. Then without any explanation, ignored my request.The second reason for me to give low rate is that its stand is very rough (not acceptable) and will damage the wood floor. The rough stand surface is not described in its product description.
