Common requests
A purchase has not arrived in my account

Request a refund
Email support@haku-core.com with the charge date. Refunds are covered by the refund policy and land back on the original payment method.
A charge I do not recognise
Charges from us read HAKUCORE. Forward the statement line to support@haku-core.com and we will identify it — please contact us before filing a chargeback so we can just fix it. Every charge we make is a one-time payment you confirmed at checkout; nothing recurs.
