Wrong Choice of JR Pass Delivery Method

Hello,

I made a terrible mistake while ordering the pass and now I am worried that we'll not get them in time for our trip:

I didn't select the 'Special One Day Delivery' (UK Royal Mail) by mistake.

Initially, I did check the correct delivery method, but after I went back to correct the misspelled name, the choice automatically reverted to a 3-working day 'Standard Recorded Delivery', which I neglected to notice.

We are flying to Japan in 3-days.

Is there a way to correct this in time?

Thank you
