Caller: Ujjain from optus

He clamid to be from optus as I have been getting hacked .. he knew my phone was not in my name and knew my name ......

It is optus

Caller: Optus

Optus calling to confirm order details. Sent an SMS verification and link which were both legit

Caller: Optus

I received a call from Steven in the Optus team on this number on 29 December, with an Australian accent and asking if I had the time to discuss the recent Optus data breach court case. I asked him to contact me tomorrow instead, and in the meantime I contacted Optus about the number (02) 9174 4000. Optus verified the call was legitimate and that I can safely continue discussing the matter with him.

definitely a dodgy call centre claiming to be optus , definitely an accent from the sub-continet of bombay and pretty rude. Do not pick up and if you do tell them to gtfo.

Got a call & message from "Jemer" @ Optus. Apparently they have completed my request - not sure what the request would be.
Whilst the message did come through amongst my other Optus messages the actual call did not display as being a call from Optus, just showed the number (02) 9174 3000. The message received had a link for me to clink on (Don't worry I haven't), I never answer a call I don't recognize and always search the number when I can. I am glad I did especially after reading everyone's comments in relation to this number.

Caller: Optus customer resolution centre

This is the Optus Resolution Centre and genuine as far as i know. They resolve Complaints that you have made although Indian representatives.

Exact same thing here.
I personally rang Optus customer services myself to have an issue resolved with my account, then received a call from this number mid way through whilst still in the middle of talking directly to an official Optus rep.

Caller: Optus

Suppose to be from Optus about a complaint i had lodged about the Internet,there were kids in the background making a racket and strong Indian accent,the answering machine took the message definite scam !!!!

Call from Optus to up sell to me.

Caller: Optus

Went to voicemail - Optus calling following up on an issue I logged yesterday. Gave correct reference number.

Caller: Claiming to be Optus (02) 9174 3000

I ordered a new phone online from Optus, about a week ago. Today I get a call saying they are from Optus wanting to confirm my details. I gave them my DOB and surname. I didn't think anything of it. Till they just called again asking the same thing. I said no . He said we need to confirm your identity. I said not now call back later.... I will be blocking them. I feel so stupid. I never get scammed.

Caller: Optus

Didn't know who it was so didn't answer. On checking realised it was from Optus. Like previous folk I don't answer calls from unknown numbers.

Caller: SCAM

Heavy Indian accent and can hear other telecommunication’s in the background. Sounded like the usual scam telemarketers. Could not understand them and asking for my personal details. If this is legitimately Optus… you sold your selves out to a foreign country who’s know for their scams. I can’t trust Optus anymore.

Caller: Optus level 2 support monkey

This number appears to be very well spoof targeted by those with less than honourable intentions.

This is very unfortunate, as it can be really, OPTUS level 2 backroom support (please keep this in mind before you issue any profanity).

OPTUS know this, yet their level 2 backroom support.staff persist in asking for all the exact same identity info the nasty people want and need to go about their nefarious undertakings.

Recently staff are less offended, when I push back, simply offering to pass "small" stuff by SMS, "larger" stuff via the account's preexisting email address.

Remember always maintain a zero outbound information policy, but be polite about it.

Caller: Optus supposedly

I suspect that these scammers somehow have access to Optus database. I did have a chat via the Optus app about an hour before the first call came from this number. They've left a message saying trying to reach me about case number xxxx but I was never assigned a case number. The caller sounded like a lady with an Indian accent. Potentially may have been former call centre staff who have somehow retained access to our data.

Caller: Optus - it's legit

It's not a scammer at all call the number back it's optus. Have had them call me via this number when my phone went dead

Caller: Supposedly Optus

Call from this number, I answered and was met with silence. I accidentally called back when searching number on my phone and got a “this is Optus enter the number” message. Obviously spoofed number.

Caller: Optus

I got a call from an unknown number, so I didn't answer it. I checked online whether this may have been a known scam number.
A message was left. It was Optus responding to a complaint I made a few days ago about how they would resolve the complaint. The caller knew details of the complaint and responded to matters I had raised. The caller did not ask me to call back, or go online etc. I take this as a legitimate call.
I am posting this as I have read a number of comments above, where people suspect this number to be a scam number, as in my case it seems to have been a legitimate call.

Yeah I agree, this is legit number, they called me about ongoing issues with the cabling I require to upgrade my NBN, the guy was all over what had been happening at my place.
