Contacted by the same person several times from various numbers (03) 9181 3370, (03) 9352 6651, (03) 9333 5979). Trying to scam information about my details under the guise of being from the "NBN" and Telstra but couldn't provide me with the contact details of the company they work for. Offered their phone number on several occasions.

My new strategy for dealing with people like this is to keep them on the phone for as long as possible. There's nothing more annoying for a scammer to have a lot of time taken up to no avail.

Good luck
