Everything you've bought is in your Offerrole account, under the e-mail you used at checkout:
My purchases (/applicant/purchases) — every order and its receipt. Subscription (/applicant/subscription) — your plan, next charge, card, charge history, and the Cancel button. My orders (/applicant/orders) — add-ons such as resume reviews, and their delivery. My applications (/applicant/applications) — which applications have Priority Review.
Something wrong with any of it? Every receipt has a Request a change link, or start at /help/change-request.
Send a change request: billing mistakes our records prove are refunded automatically, and a person answers the rest within two business days.
