Your information turns the case even more difficult. You were supposed to receive the 5 BTC, but you confused the receiving address. That means the 5 BTC was owned by another user and not by you. In this case, how can you prove that? What evidence you have that the another owner should send the 5 BTC to you?
So the address 1JYC3GbbhHiYKkZkPV2PhsdYPPDAUjjomS is owned by you? Do you receive funds from Deepbit mining pool?
