It's scam, i got called from this number and he said he call from optus company

Number calls at same time of day. But has started calling at night when its late. Blocked their number. Problem solved.

The same number calls at the exact same time EVERYDAY! they never leave a voicemail and its blank when i answer!
so annoying!!!!

Calls daily and hangs us

calling once every day for a week without leaving a message

spam

Just answered the call and spoke to a guy saying he was from NTC who was a provider of Optus. Ran through all my details and got me to say the year I was born. I then stopped him and asked if I could receive a call back tomorrow and he said he was calling from Victoria and would allow time difference but area code is WA. DODGY!!!! Next stop, calling Optus direct!

Had this same number ring me for the last couple of days. I didnt bother answering but thought id google it. Glad i didnt answer .

They have been trying to call me for over a week now. I checked this website which revealed its a scam caller so definitely not answering or calling back. Just friggen annoying!

They are NTC Voice and conduct telemarketing for other businesses. I rang the number back and the recorded message said you can opt out by going to ntcvoice.com.au/contacts and selecting opt out. So I did. I also blocked them.

called twice and never talk to me a waste of time

Answered once and someone allegedly from optus was asking me if i was happy with my service, 3 other times I have answered and they hang up straight away, so I don't answer any more

Got a couple of calls, but no mesages left-Will block and ignore

they called me yesterday and today, i picked up today, an indian guy asked me how satisfied i was with optus and checked all my personal details, even read my previous address, then tried to promote this optus wifi plan.
i googled it then i saw this website, but i checked with optus , the official site, they actually have the wifi plan.
so i am confused......

They have been ringing me for a week or so now. The few times I have picked up they have just hung up straight away. Annoying.

Constantly call, leave no voicemall, ID says they are calling from Perth, looks like a scam

This number has called me every weekday for the past two weeks & always while I'm at work so I've never been able to answer - such a nuisance!!

I have received numerous calls everyday and no messages. Are reading other comments obviously some scam call.

Spoke to Pommy guy who knew all my Optus account details and said was just checking if I had a relevant discount. He repeatedly asked me questions which I avoided saying 'yes' to. I found the call super dodgy, and told him.

Received same message. How do you block number on mobile
