I called back number (03) 9452 6957 rang 2 times then goes to busy tone.

A slight pause when answering, then they say "is this XXXX? I'm from something or other electricity company and I can save you 42% on your bills.

I requested they remove my details from they database and they hang up on you.

Frustrating, have blocked this number until a new number calls me instead!

This number has called so many time don't know it it's creepy

have tried calling back many times but nobody answers, it just goes to a voice recording. The recording sayd something about an extention line.

Didn't recognise the number when I was called and didn't pick up
Left no message.
