Caller: I don’t know

If I receive an unknown caller, I will not answer
& if they leave no message on my voicemail.
It means to me that this is not someone I know
& possible scam, so I block this number straight away!

This is a scam. Scammer called saying he was from the government and that I was entitled to an incentive for power and gas. I played along and said I had solar. He asked what is it connected to gas or electricity. I said it’s standalone. He said it had to be connected. I said it was a standalone. He asked what brand of system I had then. I said solahart. He went quiet for a bit then said in a hurry.“you are all good and don’t need” then hung up.

I agree with Frankie, no message, I spammed the number
