WRITE A REVIEWFrequently Asked Questions
Why did the call from 02 8359 9799 switch between English and Chinese?
Robocalls often use low-effort, bulk messaging strategies that play the same automated recording to many recipients regardless of location or language preference. The mixed-language approach on 0283599799 suggests the operator is running a mass campaign rather than targeting specific callers, making it typical indiscriminate spam behaviour.
Is 02 8359 9799 a real business number?
The number 0283599799 is allocated as a local service to Symbio Networks in NSW, so the allocation itself is legitimate. However, legitimate allocations can be spoofed or misused by spam operators. The robocall content reported suggests the number is being used for unsolicited automated calling rather than genuine business communication.
What should I do if 0283599799 calls me multiple times?
If you receive repeated calls from 02 8359 9799, block the number immediately in your phone's settings. Then report it to ACMA at acma.gov.au - multiple complaints about the same robocall number help ACMA identify and take action against spam operators.
Can I call back 02 8359 9799 to ask them to stop?
No - do not call back 0283599799. Robocall operators often use callback requests as confirmation that your number is active, which can result in more spam calls. Blocking the number and reporting it to ACMA is the appropriate response.
Why do robocalls use multiple languages?
Robocall operators running mass campaigns often use generic, multi-language recordings to cast a wide net across diverse populations. By mixing English and Chinese, a single robocall to 02 8359 9799 reaches both English and Mandarin/Cantonese speakers, increasing the operator's reach with minimal effort.
Is this number dangerous or a scam?
The single report of 0283599799 describes typical spam robocall behaviour rather than an active scam with false claims or financial requests. However, robocalls are a nuisance and a vector for scam attempts. Blocking 02 8359 9799 and not engaging with automated calls is the safest approach.
