Two contributors have reported calls from 02 8359 9739 (also written as 0283599739) with concerning activity. The calls come from a NSW local service number allocated to Symbio Networks, yet contributors describe fraudulent behaviour typical of scam operations rather than legitimate business communication.

What Callers from 02 8359 9739 Do
The behaviour reported from 02 8359 9739 is deliberately evasive. Rather than a normal business call or even typical telemarketing, contributors describe the caller simply hanging up without attempting to leave any message or explanation.

One contributor noted that 0283599739 was already flagged as fraud elsewhere, suggesting the number has accumulated multiple fraud reports across different platforms. This repetition across reporting channels indicates the number may be operating as part of a wider scam network.
