Do it yourself
Cancel Cerebelly yourself
TLDR: Open Account Settings and click Cancel by 11:59pm Pacific the day before the order processes. A late cancel still lets that order ship, and the stop starts after it.
Cancel in Account Settings
Cerebelly bills the box.
- 01Log in.
- 02Open Account Settings.
- 03Click Cancel on the subscription.
- 04Finish any survey they show.
Do it by 11:59 p.m. Pacific the day before the order processing date. A subscription is billed every 14 days until you cancel. If you miss the cutoff, that order still processes and the cancel starts after it. You can also email support@cerebelly.com. They may swap items if something is out of stock.
Mail a notice
You want it on paper.
- 01Write that you are cancelling, and include the email on the account.
- 02Mail it to Cerebelly Customer Service, 3336 Arapahoe Road, Unit B, #287, Erie, CO 80516.
The terms say a notice by registered or certified mail counts 3 business days after it is sent. Overnight courier counts 1 business day after it is sent. It still has to beat the cutoff or that order processes.
How to know it worked
- A cancel before the cutoff stops that order.
- A late cancel applies after the order that already processed.
Watch out for
- You are not charged a new price on an order you already placed. A higher price applies to later orders.
- If they cancel you for breaking the terms, you cannot sign up again under a different name.
Cerebelly refunds
- If they agree a refund is due, they say it is processed in about 5 business days and shows on the card in 5 to 10 business days.
