Deleted Wire transfered funds

Last night i received a wire transfer and it was credited to my account. I did some online banking and transfered part of the money to another account. I woke up this morning to an alert that my account was overdrawn. The wire transfer that I had received the night before had disappeared completely like it never had happened. I had to transfer money into the account to cover the overdraft and then to add insult to injury, I had a B of A Visa bill due to be paid on the 9th through bill pay and it suddenly was paid this afternoon. I'm not a happy camper.
