False alarm, i got them back ahhhh that was scary i thoughtthey was gone for good
Blockchain.info web wallet is full of bugs, yesterday I got email with payment received notification but actually I have send some bitcoin out of my wallet. 
And also in the transaction history it was showing -0.30BTC but in reality I have only sent 0.02BTC. However I haven't lost anything with that because it was only a visual bug. Avoid using them and search for better alternative.
