it might be the service. I sent it to the intended wallet and my sending wallet says i sent it to my intended wallet, and theres no history of it even getting there on the intended wallet, but on BE it says theres a sent trans. with all of it sent by the intended wallet.
Some services constantly move coins around, I don't know where you deposited coins too but it's likely if you requested a withdrawl from that site you'll get the exact amount of coins. Also check the account balance on that site, it'll probably still say the 1.15btc.
So in short, It's likely you deposited to a site that has 1 wallet and it assigns you an address. Now when they send funds to someone who withdraws they don't control which addresses funds come from. But when you withdraw, it'll still give you the coins you deposited in full. So if you check site it'll show your balance, but on blockchain it'll show that coins got there but moved.
That's standard on things like coinbase, gox, 999dice, satoshi dice, primedice, etc.
Don't panic, your coins till belong to you. They just move around due to the structure of the site, and how they have their bitcoin wallets setup. (1 total wallet, or 1 wallet per user)
Just some help, If you really want to tip 18zyYKUFB8RBvxtr8U6rS4qBKGJ8rMR4xX
