Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.
Please ensure that your payment method supports the following:
– Payments in USD $
– Supports subscription-based payments
– You are not using a prepaid card
– International payments are turned on
If everything from the above is enabled and working, you can also try using other credit cards instead. You can also call your bank and ask what’s stopping the payment to go through and request them to approve it on your end.
I hope that helps. Thank you, and looking forward to your update.

This is the erro I receive
Hello,
If you are using a Proxy or VPN, please disable that and use your actual ISP to make the purchase.
If the issue still persists, please provide the last 4 digits of your card or the email address you used to purchase so we can locate the transaction to check what happened. You can add them in the sensitive data section

It is completely secure, and only our support staff has access to that section.
Looking forward to helping you.
Thank you.

Hello,
You seem to be using a Proxy or VPN while making a purchase. That is why your payment is getting declined.
You are using an Indian credit card but the payment being made is from Oman.
Please use the correct details while making the purchase so it can go through.
Thank you.
