left a weird message

I called back number (07) 3171 3855 spoke to maria and she said company name is australian financial group doing telemarketing for superannuation .

When they rang, I had to say hello three times before a call centre kicked in. Some bullsh*t about superannuation insurance. I get that it's important to have it but get on ya bike

That's what they called me about to. Wouldn't leave me alone. They new my contact details, from my name to where I lived... weird and called me back twice the next day.
SCAM

2 phone calls in two days, they do not respond when I pick up.
surely another scam
