Yep, keep getting calls, have never answered and they never leave a message, now blocked.

called twice as soon as i picked up it hung up on me. NTC Voice Solutions voice mail unman WTF

I'm also with Optus and I've had this person call Monday 8th Feb after 5:00pm (QLD) and today, Wednesday 10th Feb, around the same time. I've never answered. Just let it ring. Won't after reading these comments.

every day this number calls....they always hung up and they always leave no voice message even tho they have gone to my voice message.

Had a plan phone with Optus for 3 weeks on a brand new number and this number hasn't stopped calling me..........

This number has been calling almost every day for the last few weeks. I haven't answered because I 'reserve my right to screen' and they never leave a message. I am an Optus customer so guessing it's something to do with that. I will block the number now.

This number has called me every day for about three weeks

won't stop calling

I keep getting missed calls from this number, I have answered 3 of them but they hang up after 2 seconds.

Same as above. Rang me several times over 3 days and always hung up before I had time to answer. Definitely dodgy.

continuously calling me and hanging up before time to answer

Received a call the other day no one talks for like 10 seconds. Then tried to upgrade for Optus phone. Had no idea about my plan didn't know that I'm paying a handset fee, then he said he will do my research and call me back. Never heard back. Definitely a scam.

They called saying from optus, wanted my date of birth, told them not happy to give this information over the phone and they said thank you and hung up.

They could be phishing for for information to port your mobile to steal your bank details

same here, no one answers, just hung up

This number calls me every other day, just another dodgy scam attempt as far as I can tell.

Similar to above. Calls then when answered hangs up. Last time I researched similar 08 number doing the same about a year ago was also company NTC.
Seems like they may be a dodgy agent of Optus.

Says from Optus, but said I had a business account when I don't.

Same as above. Calls, I answer no one is there. Figure it's computer generated calling. It's getting extremely irritating.

Keep getting calls from this number & it either hangs up or is silent

Have had same experience as above telemarketers
