Change bank when have forgotten old bank details

[joekerry667-2]

I cannot recall my old bank account details - which proceeds from sales amounts were paid into.

I cannot  change to new accont (can add details of new account but not confirm its use) unless I enter old account details - which I don't have anymore.

What do I do please?
