Cancellation FAQs
What is the fastest way to cancel Costco?
Call 1-800-774-2678. Follow this order: 1) Confirm the Primary Member; 2) Choose warehouse or phone; 3) Request cancellation and refund; 4) Keep the refund record. Do not leave after merely submitting a request—continue until you can see an effective date or receive confirmation.
What should I prepare before cancelling Costco?
Have the account holder’s name, account number, billing email or service address, and requested end date ready. Check the company name on your statement so you use the correct billing route. The Primary Member must make the request. Automatic-renewal refund timing can differ from full membership cancellation.
When should I cancel Costco, and when will billing stop?
Timing rule: No advance notice stated. Billing outcome: Membership access ends when cancellation is processed. Act before the stated cutoff, save the displayed end date, and check the next statement rather than assuming the request stopped an already scheduled charge.
Will Costco charge a fee or give me a refund?
Cancellation fee or remaining balance: No cancellation fee stated. Refund rule: Costco states the membership fee is refunded if the member is dissatisfied; warehouse cancellation provides an immediate refund. Ask the company to state the final charge and refund separately in writing; cancellation alone does not automatically create a refund. Equipment: Return any membership cards if requested.
How do I prove that I cancelled Costco?
Keep cancellation receipt, refund record, membership status. Save copies outside the company’s app or account in case access disappears. Your proof should show the request date, effective date, affected service, and confirmation or reference number.
What should I do if Costco keeps charging me?
First compare the charge date with the saved effective date. Contact Costco using the link or contact details above and send one clear timeline: cancellation request, confirmation, promised end date, and new charge. Ask for written correction and a refund. If the company does not resolve it, promptly give the same evidence to your payment provider and ask about its dispute deadline.
