Based on the provided information, it appears that the caller with the number +64210289972 made a ping call, which is a type of call where the caller hangs up immediately after the call is answered, often to verify the recipient's phone number or to trigger a callback. The caller's message mentioning pressing 2 if the recipient didn't log in suggests that it might be an automated system, possibly related to security or authentication. However, without more context, the true purpose of the call remains uncertain, and it could be a scam attempt. The lack of clear identification or explanation from the caller raises suspicions about the legitimacy of the call.
The message instructed: if you haven't logged in, press 2, but it offered no details about who was calling or which service required login.
