Yellow Sub Trading false advertising

Be careful of Yellow Sub Trading. They sometimes engage in false advertising. I had seen a bikini set with BLACK strands on their site and bought it and when i open my package it has BLUE straps. I contacted Nasir and told him my predicament and he said I cannot return it. I get that it is swimwear but I did not ask for that one. If I knew it had BLUE straps, I wouldn't have bought it. Now Nasir is ignoring my emails.
