Green Energy Gov't BS - don't like you asking who they work for though

Caller: Some rude guy

As other users mentioned, the guy was aggressive and had my full name when I asked before confirming where is he calling from he responded with an angry voice "forget it" and hung up.
Tried dialling to see if anyone responds line busy. Worth noting that while talking for a few seconds I heard my voice echo in the background and also heard other people speaking like telemarketing of some sort.

Scam caller spoke with foreign accent phishing for personal details

Looks like I made the correct decision to not answer this one- no message left- blocked

missed call.
