I want to use a different current account from the one I gave when I filled in the switch form.
How can I do it?

I've just checked with the team, as I thought this was a bit odd, and the good news is you can now change this in MyOVO!
It's a bit hidden, but go to your account, then go to My Profile. About two thirds of the way down the page, you can update payment details! It's there!
I've updated ITGeek's answer too, so its fully correct and super helpful to others that may ask the same question!
