HELP!

Can someone please help me out. I sent an email to Token Store but no response yet. I deposited ETH to my Token Store account but it does not show up. Shows on Etherscan as success with 350 Block confirmations after a couple of hrs. I then cleared my internet cookies/cache and re-started & imported my account. Now even the previous balance gone to 0! Any way to get it back?

PS. Looks like a scam exchange?!
