Responsibilities

I´m in charge of our firm account. My boss did a mistake not marking a used TAN before he went on holiday...
I used the TAN twice again: Now our company account is disabled! I have a problem now.
Please, any good advice will work ! What can I do? (I have a new TAN-list, but must sign (per hand) a form.
I am not my Boss! (but his right hand, he is in Spain.)
Any ideas? (rethoricle question)
