www.bestmysneakers.com review: They didn't deliver orders and didn't reply

I purchased sneakers from the website www.bestmysneakers.com. I was really disappointed, ‘coz the staff didn’t communicate with me. I placed my order 5 months ago, but these scammers still haven’t delivered it. Also they didn’t reply to my complaints. I have no idea what to do now, so please maybe someone can help me. I wonder if there are people, who have the same problems and what have you done in such situation, please post comments.
