Sound like an online wallet but business is currency exchange. What I read from others that you don't own the private key so the brand name (freewallet) is misleading. Fortunately I have never used them but the story heard about them were not too pleasant. I have no idea how you are going to recover your funds but I think you need to create enough buzz so that they feel forced to look into your case and pay you back.

Start with creating a type 3 flag and update the OP using the correct format. Format is here: https://bitcointalk.org/index.php?topic=260073.0

You will need to invest decent amount of time in this forum to follow up your case and also find any other forum that deals with currency exchange issues.

Good luck mate.
