Write to us

Telegram, fastest: @cryptocardex. Best for a card that is not working, a top up that has not arrived, or a declined payment. Tell us the last four digits of the card and roughly when it happened.

Email: [email protected]. Best when you need a written record, or for billing, privacy, compliance and business requests.

By email, put the topic at the start of the subject line to get a useful answer faster:

What makes an answer faster

We cannot look anything up without knowing which account it concerns. Please include:

  • the email address your account is registered to
  • the last four digits of the card, if your question is about a card
  • the date and amount, if your question is about a payment or a top up
  • the exact message you saw, if something was refused

Never send us a full card number, its security code, or your password. We will never ask for them, and anyone who does is not us.
