Almost identical number to that used by Indian call centre acting for Skytech Group selling hotwater services. I did not answer. No message left. They try 2-3times per day. Persistent.

Caller: "John", claiming to be about "Government Energy Program"

Spam about "Government Energy Program"

caller did not leave message

Had this same call last week from an 02 number. Free hot water pump from the government. Got quite abusive when i told them i knew it was a scam and to lose my number. After i hung up they continued ringing me consistently till i just unplugged the phone

Doesn’t leave a message and, If you ring back, an American voice tells you that the number is “currently unavailable”
