Newport News Return Policy

I purchased a dress from this company on 2/2/09 for an upcoming wedding and paid with my Visa check card. When I received the dress, I wasn't happy with the color or fit so I returned the dress vis UPS. Today I realized that I had not seen a refund come through. I called Newport News and was told they received the returned dress on 2/17/09 and that it would take 4-6 weeks for me to receive a credit for the return. The man on the phone said there was no way to speed this up. I have since sent 2 emails and the response is the same. 4-6 weeks for a refund. I paid almost $60 for this dress and in the current economy, 4-6 weeks is really a long time to wait for a refund. I recently retuned an item to Target that I purchased online and received my credit in less than a week! What is going on with Newport News. This really seems to be an unethical business practice!!
