I think you dont use 2factory with your mobile phone ?
And you can see the transaction in the blockchain just inster your adress here
https://blockchain.info/looks like you got hacked becourse blockchain never lost any coin !

2FA was used (enabled). In first post I posted a link to that transaction from my wallet.
I see above you 2 people mentioned about the 2FA has been missed out for encrypting wallet. Instead of that you need to what is actual happened when using the blockchain wallet mate.
I faced these kind of situation once. If you want to logging into your wallet. Always you need to check that whether it is luxamburg encrypted and with the correct URL. If you do not miss both the things you will be able to secure your wallet more than expected.
