For a faster response

Describe the issue and include your registered email, approximate time, and browser version. For payment issues, include the Waffo order or transaction reference, but never send card numbers, passwords, identity documents, or full PDF contents.

Expected response

We normally respond within three business days. As a product operated by an individual developer, responses may take longer during busy periods. Mark the subject “Urgent” for an active duplicate charge or account-security concern.
