No product, No communication

I purchased a set of headphones on dx.com in the first week of January.. I was meant to receive delivery by the 13 of January. Now over a month later and I've got nothing.. I've tried contacting them and nothing. Sent mails and nothing.. Im begging to accept I've been scammed. Please be careful when dealing online especially with sites you don't know well. I've learned my lesson here and won't make that mistake again. I might not get my product or my money back but if I can save someone from making the same mistake it would be ok. They look like a really legit organization but it's just a scam.. Be careful guys.
