Lightake.com scam?

I just bought 5 items from lightake.com about 3 weeks ago. First at all, they make false advertisement because they announce they have some items in stock when they dont have them really. That's why they offered me, to send me 3 items instead of the 5 i originally bought. Unfortunately i acepted, and that was my mistake. When I received the shipment via DHL, it was incomplete: the main and most expensive item was missed. After looking to all the complaints that they have in their web page related with that item, I believe that they didn't send it because they didnt have it in stock. DHL told they didn't have any problem with the package. Of course customer service from lightake.com, told me that they weren't responsible of the missing item, so i beg them to at least claim for the inssurance amount if they weren't, but they answer me that they didn't have any invoice... lol which serious company would answer that?... Well i made my payment via paypal, and i opened a dispute to get part of my money back. Could you help me with some info related with that domain? Any advice would be very apreciated. Thanks in advance for your time.

Sorry if my english is not good enough
