Tech Support Impersonation Reports for 03 7305 2300
Seven contributors have reported suspicious activity from 03 7305 2300 (also written as 0373052300), with a clear pattern of callers impersonating IT service providers. Two separate reports specifically mention callers claiming affiliation with IT companies, requesting to speak with business owners or managers about technical support needs. The number is registered to Symbio Networks Pty Ltd in Victoria, yet reports suggest the callers are misrepresenting their identity or the services offered.
The impersonation tactic appears deliberate. One contributor noted that when 0373052300 called their business, the caller "demanded the manager about tech support" with a heavy accent and immediately felt suspicious. Another report describes a similar approach where the caller "claimed to be from an IT company" and specifically asked to speak with the owner. These patterns suggest a coordinated effort to gain contact with decision-makers in small businesses.
What Callers from 03 7305 2300 Say
Contributors who answered calls from 03 7305 2300 report callers using heavy accents and employing direct, demanding language. One contributor received a call where the person "tried to sell website redesign" but "sounded sketchy" throughout the conversation. The aggressive approach of immediately requesting the manager or owner suggests these callers are trained to escalate quickly to people with financial authority.
Beyond the live calls, one contributor received a robocall voicemail from 0373052300 featuring "a woman just saying hello with overseas accent," which the contributor identified as a "classic scam call centre" pattern. This automated voicemail followed by targeted impersonation calls on the same number suggests multiple scam tactics operating from the same source.
