Anyone have any experience returning items from Cubezz? They sent me the wrong color of cube. I emailed them and they acknowledged some inventory error, but in two emails from them they only said to send it back, not how (at least not in a way I could understand). I assume most stores would give me a return label since they cover return shipping for wrong items sent, but I couldn't understand their English in their response. If I sent it back using USPS, it would be $12, as much as the cube itself.
