www.lishaninc.com review: wedding dress! 1

Brought a wedding dress from this website, lishaninc.com. Feeling very good about the wedding dress, in good quality. However, the dress was a little big for me.So I wanna change one. The company promised to refund my money, but I received it in 4 days. They said that this is International transaction, the process need 4-7 days. I didn't know it's true or not.
