Approach calls from unknown numbers with caution, especially those using automated voices or hanging up abruptly. Reports indicate this line often features a robocall pretending to be from immigration authorities, warning of missing documents to create panic and extract personal info. Another pattern shows silent calls that disconnect quickly, repeated over days, which is a common harassment tactic or prelude to scams. Never share details like passport numbers or addresses—legitimate agencies don't cold-call for such matters. Block the number immediately on your phone, enable spam filters via your carrier, and report to authorities like the FTC or ACCC if in Australia. If concerned about real immigration issues, contact them directly through official channels to verify.
There is no voice when they call; they hang up, and this has happened many times over the past days.
