This is a number used by scammers who are pretending to call from the ATO saying you need to ring about tax invasion charges and if you don't ring there will be a warrant out for your arrest.

ATO scam alert

Got recorded message about tax evasion/fraud ring this number or warrant for arrest will be issued. Rang ato and reported this scam

Caller: DEFINITELY SCAMMERS BEWARE!!!!!

Received a call from a woman who gave me a name and an employee number from NBN Co, I went along with the conversation long enough to be passed to a "senior person" to get my registration details, needless to say he couldn't answer my questions nor give me points of reference online to the point he hung up on me as he obviously realised I was onto him. What I did get was they wanted to offer me 50% off my phone account for paying the next 12 months UP FRONT!!! I even rang the phone number back and they answered it as NBN Co so this is obviously the hot option for these guys at the moment. Most certainly scammers!!

Caller: NBN using (02) 4407 0027

Got a call from Susan Brown Operator No. 8600058 (Probably not her real name) about NBN connction.
I ended the call. Received a call back from a 'John' who referenced Susan's previous call and picked up where she left off. I hung up on him after saying I wasn't interested in logging onto my computer. He then rang back twice - both calls going to my answering machine. The second time he left an abuse message. I called back the 02 Sydney number and got Martin No. 10001138 who knew of Susan but not John. Seams to be an interconnected NBN, Microsoft, ATO scam centre.

Received a call from this number saying they are from NBN.

Indian scammer saying he is from NBN.

They called my 84 year old mother claiming they were from the NBN and demanded payment of nearly $300 or her home phone line would be disconnected. They were very persisted and kept her on the phone for 40 minutes until she gave them her card details for payment. She called me very distressed and I immediately arranged with the bank to put a stop on the card. these low life people pray on the elderly and use fear to get what they want.

Caller: Said he is John Anderson from Windows support

Scammer
We hung up and he called straight back
Very persistent so we hung up again

The old Microsoft technical services b.s.

Received a phone call from (02) 4407 0027 someone by the name of Mark Anderson on 10th July 2017. The message said that a complaint has been made against myself for tax fraud / tax avoidance, a warrant is about to be issued at the Federal Court of Australia. An urgent return phone call was also requested. This is a SCAM WARNING. Do not ring them back!

I have had this call twice already and have reported it to the ATO. The ATO advised if they do call they do not call from an unlisted number and do id checks and give you a number and that you can find on their website. if you call this number back they will hack into your phone and obtain your personal details. DO NOT CALL THEM BACK!!!!

Yep got the call, went to voice mail... dodgy as hell.

Yup, same here. just received a call from this number.

got a recorded message regarding tax evasion. Returned the call on a different number and asked who the number was and they said ATO. Scam
