Typically refunds clear on our end in 24-48 hours, but based on the original payment method and your bank, it can take a billing cycle(3-4 weeks) for this to be processed.
If your refund still hasn't been applied after you receive your next bill, please let us know via the Contact Us page and we'll be happy to resolve that for you.
Please note, refunds (and charges) will appear on your billing statement as TeePublic.
