Do calling credits expire, and can I get a refund?

You buy a balance and calls draw it down. There is no plan, no monthly fee and no commitment, so a month where you make no calls costs nothing. Billing runs per minute from the moment a call is answered, with part of a minute counting as a full one, which is the same rounding the underlying carriers use.

The price for a call is resolved from the digits of the number before you dial. The keypad shows the full per-minute price for your account, including the Professional addition when it applies. That displayed price is what comes from the balance. There is no separate connection fee, and the keypad states that part of a minute counts as a full one.

A call that rings out, hits an engaged tone or fails to connect costs nothing. You pay for connected time only, so an unanswered call to a number that turned out to be wrong is free.

A person, phone menu, hold queue or voicemail counts as connected time and is billed from that point. If a call record shows a charge without a connection, contact support so we can review it. A top-up you have not spent any of can be refunded within 30 days of paying for it. Closing an account gives up whatever credit is left on it, so ask before you close rather than after.
