Apple Pay sending receipts to wrong email

i recently changed my email address and successfully switched my apple id info over to the new address but i keep getting order confirmation emails sent to my old address when i use apple pay. i have looked everywhere but can't figure out why this is happening. my old email address doesn't show up anywhere on my apple account page anymore, instead it shows that my address is the correct current one. but... i keep getting apple pay confirmation emails at the old one. super frustrating! please help!
