Review This seller is very fraudulent

Do not buy from him. I bought a studio background from him, they were meant to be size 10 by 20 but he sent 10 by 15 instead. After, I called him and did a video of the background for him to see, he accepted he sent me the wrong one but refused to refund part of our money nor sent a replacement. He even refused answering our calls nor responding to our messages.
