About OneCard
Most things on OneCard are done inside its own app, this being a mobile-first metal credit card, though the company also runs a toll-free line and email for statements, payments, limits and card blocking. Those official contacts are listed here so you reach OneCard itself.
If the card is lost or stolen, block it in the app straight away or call the line. Grievances can be taken to the official grievance email, and any number you find elsewhere claiming to be OneCard support should not be trusted.
