Is promdressmarket.com a good place to buy a dress online?

I found the dress that I want on promdressmarket.com a lot cheaper than on other websites. I bought it online, and they sent me back an email saying that they want my mesurement and to show what kind of color i want my dress to be. I sent the mesurements 3 days ago, but i never got back an answer from them, and they also don't have a phone number that i can call. Did any of you buy a dress from this online store? Do you think that I would be able to have my dresss at my house before prom which is in 3 weeks? Do you think I would be able to get my money? tks
