This 'Telstra' scam is happening again - we have had our number for 30 years and received this is what we have recieved:

Received a text and phone calls from "Telstra" ??? wanting me to ring them on 1800 number about my account. My bill is always up to date and no issues so was hesitant when I rang the number. Foreign voice became aggro when I refused to give address after telling him you have that information because you send me bills. He told me a person was wanting to have access to my phone but when I checked with that person he said it was bullshit and a scam. Glad I didn't give them information.

Following an initial phone call a month or so ago from someone (not easy to understand) claiming to be Telstra, I hung up. On 16 October a very legit looking letter from ''Telstra'' referring to earlier call and asking me urgently to call this number. It had my correct address, my account number, bar code. I phoned Telstra on their 13 22 00 customer enquiry number, had to identify myself in the usual ways. Their response was that it was a scam, that they don't send such letters, and that it had been reported before. No action taken by me now other than reporting to Scamwatch (ie. ACCC).

Calls from this number (1800 531 866) appear very suspicious! HOWEVER, in my case at least, the call was indeed from Telstra; it turned out that they were wanting to ascertain whether or not a person who was added to my account in 2002 (15 years ago!) should still be an authorized person (authorized to make changes, cancel my service, etc.). They gave me the name of the individual, who I recognized as a former flatmate from a long time ago (15 years, I suppose). So, I informed them that the person should no longer be authorized on my account (he moved out many, many years ago!).

Why Telstra is checking 15-year-old details on current accounts I have no idea! I also expressed my concerns over the suspicious-looking nature of the contact form Telstra - the woman I spoke with mentioned that I was far from the first person to raise such concerns, and that this (suspicious-looking) had been raised to their managers more than once.

Personally, I would have been MUCH more confident that the call from 1800 531 866 was indeed from Telstra if either:

- the call originated from a phone number that I could identify/find somewhere on Telstra's website, or.

- the communication from Telstra over a non-urgent matter (checking details that have been unchanged for 15 years, it was hardly an urgent matter!) came by a more traditional method, namely a snail-mail letter from Telstra.

Bottom line: in my case at least, calling 1800 531 866 on 5 October 2017 did indeed get me through to a person who IS from Telstra.

They have called my phone 3 times, and send texts each time requesting I call them regding my Telstra accoun. I called the number and was placed on hold with the standard telstra music??

SoundED like scammers, but are an independent investigation team working outside of Telstra.

They will be investigating a FLAGGED discrepancy in your account.

I went straight to my local Telstra dealer after the call because I did update my details with them and was worried about it.

The information was already logged and detailed on my account and they showed me, a scammer could never break into the Telstra network and write action notes on.

My account.

If your worried as the caller for their Delta (D) number.

In my case, my X wife must have tried to access the account, it was red flagged and they asked me if she still had authority, I said NO.

I got text at 12:41pm saying "Hi from Telstra, we??? Ll be calling you shortly in reference to your Telstra account. Any questions call 1800 531 866 9am-7pm Mon ??? Fri." I missed their call at 4:40pm and they left voicemail message "Casey from Telstra" and to call back on 1800 531 866. I had been having trouble with my account so almost called but decided to check here first and now will not do.

Received message on 101 messages with accent could hardly understand but got as much as " Regarding account ---- please call urgent to 1800531866 or 132200 etc etc". I always look up this site before calling any numbers back, looks like it may be a scam.

Pretended to be from Telstra to 'verify some details of my account - who is designated to change account details on my behalf'.. Called Telstra afterwards & they said they'd had a lot of queries about the same caller - definitely scammers.

Pretending to be Telstra - scared me about my account and not think is SCAM.
