2 missed calls from this number after advising Optus billing I would not be paying for internet this month as I have been unable to access my account since Monday and email accounts as well as Outlook since Tuesday. Reorted this to Optus who have done absolutely nothing. Advised them I will not be paying for a service I have not received and will be looking for another ISP.

Caller: "Raj" from Optus

Claimed to be Raj from Optus, knew my legal name. Was told my phone plan has ended. Asked if I wanted a new phone. I said no and hung up. Not sure if this is a scam but it's weird for Optus not to send me an email or use my preferred name. I wouldn't trust this. If you want to get a new phone plan, call Optus directly yourself.

Caller: Optus

I was on the phone to Optus loyalty team and the line got cut. So I called them again and I was told the lady I was speaking to called me many times but could not get through. The number was the above number which I had blocked previously. I am told by the next person that they don’t know what number comes up when the call goes through the call centre. I now know it’s definitely Optus so I have now unblocked the number! 😂

Caller: Optus (247.ai)

Phone number (whilst can be spoofed) is from Optus's 3rd party call centre "24/7". You can check who 247 (247.ai) is on the Optus Wikipedia website. They called me as I was expecting a call back from them.

Yes they sound unprofessional & scam-like but the call I had was genuine and when called back on another legitimate Optus line they confirmed the call had taken place.

So take head and be careful, but his can be a genuine Optus number.

If the number has been the same for a fair while I wonder why the police haven't made an arrest?

Caller: Supposedly "optus"

Yeah I don't like this. They should be calling from an official number that shows up as optus on my phone, otherwise it looks like scammers!

I didn't do any security questions and said I'd call them back later to discuss my bill (via the official optus number!). No way am I telling some random Indian my security details over the phone after losing all my details in the security breach!!

Caller: Claiming to be Optus

Not sure if its legit - My caller asked me for all sorts of Identification data, who gives that to a cold caller? - would not tell me reason for call until I provided identity for myself but they could not prove to me that they were Optus - this is a scammer's number.

Several calls a day from this number. No message but I can hear a call centre environment in the background. For everyone saying it's Optus, I seriously doubt that they'll be conducting cold calling after their recent debacle. Blocked and reported.

Don't answer, takes too long to connect to be legit.I tried calling back and it syas its Optus service. They call almost every day and don't leave a message. If it were Optus, they could contact you via email or send a letter to at least describe the nature of the call if it were so important. I was hacked so that doesn't help.

Caller: Optus customer centre

Optus customer centre. request calling.

Do not reply or open any message or link on this number, it is scary and open fraud, just put it on the block. The answer means the files were hacked and you will be in a dark spot too.

Caller: Jen - Optus? (or Chen?)

Received a call - apparently Jen from Optus. I asked to leave me her number and XX would call her back. This completely threw her off from what felt a scripted conversation. She gave me ph: 133937 to call (which may very well be a legitimate number for Optus but it just didn't feel right) and when I asked what the call was about it was a non-confident "re Account health check for XX". Doubt very much this is legitimate, so won't be phoning back.

Just block it.

This number left a voice message of 1 minute and 50 seconds of dead air so I don't know who it was. If it were a genuine caller, I doubt they would leave a dead air voicemail.

With that said, a number of reports on this number claim it's legitimately Optus, and a number of others claim it's a scam. Please protect yourself and be aware that it could be both. Scammers may be spoofing a genuine optus number in order to have you believe it's Optus calling you. Do not provide any information to them. If it's genuinely Optus, they will have other ways of working around this issue.

Caller: Optus hacker

Scam call. don’t answer

Just received a call from this number purporting to be from Optus, calling for our valued customers and to let me know that I might be eligible for an upgrade of my handset. I said I wasn't interested and they just hung up, rather than saying anything else. Absolute SCAM caller

(02) 9174 3000. Called and immmediately hung up. Presumed they are amping up BS to roll out future efforts or else just scammers. Dont give them any information.

Caller: Optus

After call to tech assistance with Optus who unable to fix NBN outage I was told to expect a call from a level up. After a few minutes, got 3 calls from (02) 9174 3000. On 1st 2 calls I was unable to hear atything and said 'sorry can't hear you'. On the third call it was indeed an Optus fixer. NBN to be fixed tomorrow .,. Fingers crossed !

Suspicious call claimed from Optus, call outside normal business hours

Caller: Could be Optus, could be a scammer.

It is possible that Optus's marketing team have decided to use techniques that scammers use to increase there market reach.
Scammers will often try to get you to confirm your identification and then send you a one-time pin. This technique is used regularly to obtained additional details of a possible target and to reset/re-assign account passwords or phone numbers (stealing phone numbers through e-sims etc). The one-time pin could be associated with accounts such as your bank, google account, or even your phone number. If you get sent a one-time pin it should be from a legitimate company that you have contacted and not one that has contacted you. Never give it to someone over the phone or internet as they can use it to reset your password or log into your account.

Optus, being a large Australian based telecommunications company, are likely to be based in Australia with a really good line quality. If you don't feel that the person on the other end of the line is in Australia or the line quality is really bad then that is also a major red flag.
