Spam Invoice Reports for 02 7248 2300
A contributor has flagged 02 7248 2300 (also written as 0272482300) for suspicious billing activity. The report describes receiving two calls from this number, with no voicemail left on either occasion. Following the calls, the contributor received unsolicited invoices totalling $499 via email, characteristic of invoice-padding spam tactics.
The number is allocated to Symbio Networks Pty Ltd, a local service provider in New South Wales. The pattern of multiple calls paired with unexpected invoice demands suggests this may be a coordinated billing scam rather than a legitimate service provider attempting contact.
What the Caller Behaviour Indicates
The strategy of calling without leaving a message, then sending invoices, is a known pressure tactic. By leaving no voicemail, the caller creates uncertainty about the call's legitimacy while the subsequent invoice creates a sense of urgency. Recipients often feel compelled to respond or investigate when an invoice arrives, making them vulnerable to further contact or payment demands.
The fact that 0272482300 sent the invoices via email rather than official post suggests an attempt to bypass formal billing channels and create a sense of informal urgency.

WRITE A REVIEWFrequently Asked Questions
What should I do if I received an invoice email after the calls from 02 7248 2300?
Do not pay the invoice. Contact Symbio Networks directly using the contact information on their official website to verify whether the charge is legitimate. If the company denies sending it, forward the email to the ACMA at acma.gov.au and mark it as spam. The pattern reported for 0272482300 - calls without voicemail followed by unsolicited invoices - is typical of billing scams.
Is 02 7248 2300 a legitimate Symbio Networks number?
The number 02 7248 2300 (0272482300) is allocated to Symbio Networks Pty Ltd, but the reported behaviour - calling without leaving messages and sending uninvited invoices - does not match legitimate customer service practices. Legitimate service providers contact customers about verified charges and provide clear voicemails. If you have an account with Symbio, verify any charges directly through your account portal or by calling Symbio's official customer service number from their website, not 02 7248 2300.
Can I block 02 7248 2300 on my phone?
Yes, you should block 0272482300 immediately. Most Australian phones allow you to block numbers through your settings or contacts app. For newer phones, you can typically long-press the contact and select 'Block' or 'Add to blacklist'. After blocking, any calls from 02 7248 2300 will go directly to voicemail (or be rejected, depending on your phone settings), and you won't receive notifications.
What is Symbio Networks and why is 02 7248 2300 associated with it?
Symbio Networks Pty Ltd is a telecommunications and internet service provider operating in New South Wales. The number 02 7248 2300 is allocated to them, but allocation alone doesn't guarantee the number is being used legitimately by the company. Scammers sometimes spoof or misuse business numbers. If you don't have an account with Symbio or recognise the invoices, it's almost certainly a scam. Report it to both the ACMA and Scamwatch.
Why would a scammer call twice but not leave a voicemail?
Callers using 02 7248 2300 in this reported scam likely skip voicemail to create uncertainty. When you see missed calls but no explanation, you're more likely to call back or panic when an invoice arrives, making you vulnerable to pressure tactics. This strategy also keeps records minimal - no voicemail means less evidence. The pattern of silent/no-voicemail calls followed by invoice emails is a deliberate pressure tactic designed to confuse and urgently prompt payment.
Should I contact the ACMA about calls from 02 7248 2300?
Yes, you should report calls from 02 7248 2300 (0272482300) to the ACMA at acma.gov.au, especially if you've received multiple unwanted calls or suspicious invoices. The ACMA investigates spam and scam calls across Australia. Also report to Scamwatch at scamwatch.gov.au. These reports help authorities track patterns and protect other Australians from the same number.
