no answer when called back another scammer

I called back the number 0421 148 217 and reached vm that did not mention the company name

I let it rang out, I do not answer any calls from private number or if it’s not stored in my phone, caller did not leave Voicemail so I didn’t call back!

Caller: He said Amazonia?

Asked how did you get my number? Apologised and hung up!

i called back number 0421 148 217 reached voice mail but did not say for what company.
