I ordered a replacement flap for my dog door from Ideal Pet Products. When the order came in I discovered it was the wrong part. I emailed the company at their posted return site and requested a return address since there was not one listed. After five days when I hadn't received any information, I sent another email. Still nothing. They state they take returns for up to 30 days with a full refund. It appears they are going to totally ignore my request or at least delay it long enough they won't have to take it back. I would suggest that this company isn't very ethical based on my experience.
