The male caller left a voicemail. He knew my name, but did not leave his name, company, return contact number or what the matter was regarding.

Dialler system, they took a bit for the call to connect over which is generally a scam / seller type scenario. Called back, no company introduction to confirm who they represent and sounded like a call centre in the background and not from Australia. Recommend do not answer.

Repeated calls for Solar despite asking to be removed off their call list

I had the same call today

The caller said he was from Dulwich Solutions (fake company) and was offering solar energy consultations. Scam.

They just hung up when i answered- I seem to get a lot of these types of calls from similar numbers

Called but no message left

Didn't leave message
