Hello,
Thank you for contacting Rank Math and bringing your concern to our attention.
As we’ve partnered with FastSpring, a global full-service SaaS payments platform, Rank Math doesn’t handle transactions directly. So, I would like to suggest you to get in touch with our payment provider, FastSpring, and I hope they’ll be able to assist you with this.
Here’s how you can update information in the invoice: https://rankmath.com/kb/manage-invoices/#how-to-update-your-invoice
You can use the following contact form: https://fastspring.com/consumer-support-form/
Hope that helps, and please do not hesitate to let us know if you need our assistance with anything else.
Thank you.
