Time to close the thread. OP keeps posting conflicting information(first he didn't authorize them to run his credit, then he did authorize them; didn't want two cars, then he bought two cars; etc.). The question has been answered - sue for the return of the deposit.
Of course, we have no way of knowing that a lawsuit will be beneficial, as the OP refuses to answer the simplest question of all: what did he sign?
