My business partner and I opened a DUAL SIGNATURE account, at BB & T, which required both signatures for any transactions. She and I, each, put $ XXXX the account and were adamant with the Bank Officer that we had to sign jointly and we signed a card to be filed with BB & T. On XXXX XXXX, 2015 an investor, ( He was a friend of my partner. ) came on board and loaned us {$25.00}, XXXX payable in 6 months with 5 % interest. All XXXX ( XXXX ) of us signed a Promissory Note at the bank with the same bank officer as a witness and notary. We wrote a check for a deposit for $ XXXX a lease for a building on the beach. Monday, XXXX XXXX, 2015, the banker called me and informed me, my partner had withdrawn all the money andCLOSED the account, but they were depositing my initial {$4000.00}. back into an existing account I had already with BB & T. When I questioned the banker about how my partner was able to withdraw without XXXX signatures, she informed me that as a partner she ( my Partner ) could manuever money as she saw fit since she was a signer on the account. 
I contacted BB & T corporate and they referred me to a clause stating that if was unclear, they could allow XXXX signature to conduct transactions if they are unclear that XXXX signatures were required. The same Bank Officer is the one who opened the account, witnessed the promissory note signatures, and closed the account. I do NOT see how any of this can be misunderstood nor unclear. 

Now I have a {$12000.00} check floating around out there with my signature, ( and my Partners ), on a closed account. HELP!
