How to get email from order page in woocomerce?

Question

Payment cards

I set up payment by card (MIGS Mastercard) on the site with woocomerce. I use the MIGSpro plugin. My bank requires vpc_OrderInfo to display the email entered on the order page instead of order_id. I don’t want to post a long code here, but I can’t explain it specifically)) Here is a link to the file where it’s clear what’s what www.majestyestate.com/migs.txt I almost don’t understand this, I tried several ways. but they return empty if the user is not logged in.
