I get calls twice a day- one just then at 2.30 and the other at 8.30pm from 8023 0165 , 8023 0153- how can i block them from calling

I received a call from this number yesterday, they diddn't leave a message. God knows how they got my number as it is not listed (private). When hubby phoned back there was a answering service asking to leave name and number but failed to identify themselves, Hubby just hung up thank goodness.

getting these calls and simular numbers, just the three ending numbers usually differ

I retrieved the number by pressing *10# then rang them
back. It was an answering machine(womans voice).
She didnt say what company it is.

3 missed calls to my mobile today - from (02) 8023 0451, (02) 8023 0361,(02) 8023 0153.I did get a similar thing on my work mobile to and silly me rang it to get told by pc type voice - "i had won" at that point I hung up..can we stop this

I have also been on the Do Not Call register for at least 5 months and yet today, I have just recieved another call from this number.I will be making a formal complaint through ACMA now
