Do it yourself
Cancel CompTIA yourself
TLDR: Cancel in the CertMaster account or the billing portal, or call (866) 835-8020. A stop may not apply until the next billing period, purchases are final unless a page says otherwise, and an unredeemed digital product can be considered for return within 30 days.
Cancel in the account
You opted into a recurring subscription.
- 01Sign in to the CertMaster account, or open the personal billing portal.
- 02Cancel the subscription there.
The signup page also says you can use chat, email, phone, or voicemail. It does not print the email address. The terms say a change may not apply until the next billing period. They email you before a renewal when one applies.
Call
You want a person.
- 01Call (866) 835-8020, or (630) 678-8300.
Support is open 24 hours a day from Sunday at 7:00 p.m. Central through Friday at 7:00 p.m. Central. Hours can vary by region.
Mail a notice
You want it on paper.
- 01Write that you are cancelling, and include the email on the account.
- 02Mail it to CompTIA, 3500 Lacey Road, Suite 150, Downers Grove, IL 60515.
That is the headquarters address on the contact page, next to the support phones. A copyright complaint uses the same street and suite, but the terms print ZIP 60151, and email legal@comptia.org. A cancellation uses 60515.
How to know it worked
- A stop may not apply until the next billing period.
- The terms also say subscription services expire after 12 months unless a different length is stated.
Watch out for
- Recurring fees are charged at the posted price, described as monthly, until you cancel. No dollar amount is printed on the terms page.
- Prices are in US dollars unless the page says otherwise.
CompTIA refunds
- Purchases are final unless a page says otherwise.
- A digital product that has not been redeemed can be considered for return within 30 days of purchase, if the access key was never activated. That list includes CertMaster Learn, Practice, Labs, CompTIA Labs, Learn+Labs, CertMaster CE, and LabSim.
- Start a store return from Order Status, then the Return button on that order. Partial refunds are not offered. Exam vouchers are final.
