Hello,
Thank you for contacting the support and sorry for the confusion.
Rank Math PRO (all license types) comes with a FREE 15-day Content AI Trial. This is mentioned on the pricing page as well:

We also send out an email reminder seven (7) days before the actual charge so that users can cancel the trial. We also mentioned this in our FAQs.
You can cancel the Trial at any time using this link:
https://rankmath.com/my-account/subscriptions/?tab=cai-subscription
→ Here is a guide on how to cancel your Content AI Trial
With that being said, we have initiated a refund on your Content AI subscription as requested. You should see a credit for the refund appear on your credit card statement anytime between now and the next 5 to 7 business days.
If you used a debit card for the payment, the refund might take up to 30 days to appear on your statement. Please note that refunds for international transactions can take up to 10 days to appear for credit cards or up to 60 days for debit cards.
For PayPal, it’s always almost instant.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
This is underhanded. Showing a free trial and expecting customers to go research whether they are signed up for unwanted services is bordering on fraudulent. Putting the onus on customers to read your constant emails to find an “oh by the way we are going to charge you for a service you never wanted” is totally unscrupulous.
Hello,
We sincerely apologize for any frustration caused. Our intent is never to mislead, and we strive to be transparent by clearly mentioning the free trial and subsequent subscription on our pricing page, FAQs, and via reminder emails.
We understand your concerns and have already processed your refund as requested. Your feedback is valuable as we continue to improve our processes to ensure clarity and a better experience for our users.
Thank you for your understanding, and please let us know if there’s anything else we can assist you with.
Hello,
Since we did not hear back from you for 15 days, we are assuming that you found the solution. We are closing this support ticket.
If you still need assistance or any other help, please feel free to open a new support ticket, and we will be more than happy to assist.
Thank you.
