Sammy Dress Asked for refund or item ordered but no replys Beijing Internet

I placed  order on 8/29/15 and payment was processed on 9/1/15.  They asked for my street address so I put my street address ( and mailing address ) As some shippers do not deliver to post office boxes.

it was sent to my street address and as I have no mailbox there the post office sent it back.  I spent so much time trying to track it  to try to get it back, but was told by DHL that they do not handle returns back and it probably went back to China.

I tried on numerous times to ask for the package returned or money refunded but they are no longer communicating with me.  one time after I inquired what happened to my package, they did they say it was undeliverable. Since that one message, they have stopped all communication.

This was my first order from this company and I had hoped it was legit but now I feel like they just stop communicating and keep your money if it gets complicated for them in any way. 

Is there any way I can make them give me back my money or re-send my package.  ( it took almost a month the first time it was sent).
