Hello,
We apologize for the issue you are facing while trying to purchase the Pro Plan. It sounds frustrating, and we appreciate you taking the time to troubleshoot by turning off your VPN and ad blockers, as well as trying different browsers.
Here are a few additional steps you can take to resolve the payment issue:
-
Check Your Payment Method: Ensure that your payment method supports payments in USD, subscription-based payments, and that you are not using a prepaid card. Also, confirm that international payments are enabled.
-
Contact Your Bank: Sometimes, banks may block transactions for security reasons. It might be helpful to call your bank and ask if there are any issues preventing the payment from going through.
-
Use a Different Payment Method: If possible, try using a different credit card to see if that resolves the issue.
If you continue to experience problems, please reply to this ticket with any additional details or a screencast of the issue, and a human agent from our support team will assist you further.
Thank you for your patience, and we look forward to helping you complete your order!

Hello,
Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
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
– Your IP is not a Proxy, or you are using any VPN or hosting service
Also make sure that the flag during checkout is showing the correct country at the top right corner.

If everything from the above is enabled and working, you can also try using a credit card instead.
You can also call your bank and ask what’s stopping the payment from going through and request them to approve it on your end.
Looking forward to helping you.
