No message left, also called from (03) 5751 0308 on the same day

After Christopher who stopped talking and hung up once he realised he was talking to voice mail called me on (03) 5751 0308 I suspect the same group decided to try again on this number instead. ...

This number called twice using the above and then (03) 5751 0308 the second time. They would not tell me who they were the first time unless I confirmed my name, I refused and then hung up.
Not sure if scam but with so many happening was not going to answer the second time they called me.

They tried 2 x and didn’t leave a message. Once at 6.37pm then at 7.10pm
