As mentioned on our support article How do I cancel my subscription?, every user must process their cancellation request at least 24 hours before their due date or before their trial period ends.
If you hadn’t canceled it before the end of the trial period or before your due date, you were probably automatically charged.
But if you feel that you should get a refund, please get in touch with Ubersuggest’s support team, by sending an email to support@securiwiser.com.
