We read everything and reply to genuine questions as time allows. If you are writing about a specific hold on your own card, please do not send card numbers, account numbers, passwords, or statements — we never need them, and no legitimate service will ask for them by email.
Before you write about a hold
We are an educational site, not a bank: we cannot see, release, or dispute a hold on anyone's account. The people who can are the merchant (who can send a reversal) and your card issuer (who restores your availability). The step-by-step playbook is in hold release times and the FAQ — it is genuinely the fastest route, faster than waiting for an email reply.
Corrections
If you spot an error — a rule that has changed, a deadline we have stated wrong — please tell us, with a link to the official source if you have one. Accuracy is the entire product here, and corrections are acted on promptly.
