Can you please show us some screenshots of your correspondence or the lack thereof? So that we can confirm that you're telling everything truthfully etc, you're not doing anything wrong and things along the lines of that.

I find it particularly odd that they closed your ticket without answering. I've used them for as long as they have existed, in fact they have given away so many litecoins in their launch that scamming a small amount from a nobody would be an extremely bad business decision to make.

Try to PM them on forum, like others have suggested. They are quite active here.
