This number called many times (12-15). They pretended to be OPTUS and asked for personal information. They are probably part of an identity theft ring.

Not so much a comment about this number, but telemarketers in general.
If they are not from this country and you don't want them to call back, don't simply hang up or put your number on the do not call register, be EXTREMELY racist. It works for me.
Personally, I don't care where someone is from or what they believe, but I use racism ALL THE TIME to upset these mongrels.
Only problem is, I enjoy doing it, but they don't call back, so I gotta wait for a new call centre to open up to do a new round.

I have been getting calls from this no. but told them that it's the wrong name & number, so we will see if I get them again. it's now the 5th day in a row.

who are these people? ive had 5 missed calls from them and they leave a voicemail but with nothing said and when i ring back its an automated message

Well it's not actually telemarketers, Optus has just outsourced their customer service/promotions department... but still a pain in the a**.

Got a phone call today from a guy claiming he was from Optus. i got suspicious when he asked for my mobile number. You'd think they would know my number if he just called it.anyway, he was selling me some internet package deal for my mobile.

I gos call every date from this number, then I tried to call back say ICT Group p/l and the phone hang up

stop  calling me b***hIM ONLY 11 YEARS OLD AND IM RECIEVING CALLS FROM THESE IDIOTS AND I HAVE NO IDEA WHATS GOING ON!! these people are wasting my time goshhhhhhhhhhh
