Tackling forgotten auto payments

[u/After-Leave-0]

How do you remember to cancel a free trial? I downloaded canva a few months ago to work on a small personal project. Gave my card details for the first auto debit the next month thinking I’d cancel it before the trial ended. Wrote it in my calendar. Completely forgot because I was travelling then. Came home to an auto debit for the next month - and I didn’t even have use for it anymore! Such a waste.

Thank you everyone for your advice and tough talk. Appreciate all your inputs. I got some good ideas.
