WRITE A REVIEWFrequently Asked Questions
What is a robocall and why did 03 9970 0357 leave only silence and a goodbye message?
A robocall uses automated dialling systems to reach large numbers of people quickly. The silence followed by a robotic goodbye from 0399700357 suggests an automated system checking if your number is active and monitored. These are often used to harvest confirmed numbers for future scam campaigns or telemarketing lists.
Is LetsbeMates a legitimate NBN service provider?
LetsbeMates appears to be a telemarketing operation, not the official NBN provider. If you receive NBN-related calls from 03 9970 0357 or similar numbers, verify directly with nbnco.com.au or call the official NBN hotline. Legitimate NBN issues are typically communicated via letter or your registered account, not unsolicited calls.
Why won't the caller from 0399700357 let me ask questions or speak?
Aggressive telemarketing tactics like interruption and preventing questions are designed to rush you into decisions without thinking clearly. This high-pressure approach from 03 9970 0357 is a common red flag for unwanted sales calls. Legitimate service providers allow you to ask questions and take time to decide.
Should I callback 03 9970 0357 to find out who called?
No. Do not callback 0399700357. Robocalls and telemarketing numbers often use this to confirm your number is active and monitored, which can lead to more calls. Block the number instead and verify any claimed service issues through official channels directly.
What should I do if 0399700357 leaves another voicemail?
If 03 9970 0357 continues to call, block the number on your phone immediately. You can also report repeated unwanted calls to the ACMA at acma.gov.au. If the calls persist after blocking, this may indicate spoofing (fake caller ID), in which case document the dates and times and report to Scamwatch.
Is 03 9970 0357 definitely a scam or just annoying telemarketing?
The reports about 0399700357 so far indicate robocalling and persistent NBN telemarketing rather than a confirmed financial scam. However, robocalls are often used as lead generation for later scam attempts. The aggressive behaviour and refusal to let contributors speak are red flags. Treat calls from 03 9970 0357 as unwanted and block the number.
