4 Jan 21 : A call on my mobile, there was a long pause then a recorded male voice as I was hanging up. Interesting as I haven't given out my new mobile number, except to official departments. I usually know the numbers calling me.
today 5 Jan 21: received call, didn't answer, (03) 9701 7162 which shows on here as an "energy" caller... I am assuming yesterday call is linked
thanks guys, so good to find out this info.
