Depending on when you joined, there are two ways to cancel:
If you joined before July 2017 you’ll have access to your subscriptions in your “my account” page. Click on "Subscriptions" then "Cancel"
Please note, I will be sad...
A better idea would be to let me know why you want to cancel and give me a chance to keep you on the team!
If you joined after June 2017, just contact me through the support page or messenger and let me know you want to cancel. (I'll still be sad)
