Hello,
Please share the email address you used to purchase so we can verify the account. You can add it in the sensitive data section

It is completely secure, and only our support staff has access to that section.
Please note that we don’t offer support for nulled or cracked plugins as we explain here: https://rankmath.com/kb/rank-math-pro-nulled/
Looking forward to helping you.

Hello,
We do not sell from 3rd party services.
You need to get in touch with the seller to provide you with the support & updates of the plugin.
To get PRO support, you need to purchase the product from our website.
Hope that clears up the confusion, and looking forward to helping you. Thank you.
