Caller: Mark Cooper

Bad Line, Indian accent. Wanted me to change my Telstra IP address. 100% scam, I'm an IT person

Called with Indian sounding accent (supposedly from telstra) & claimed there was a problem with our phone line causing havoc with internet in the area. He claimed we had changed our IP address & unless we do as he instructed our nbn would be cut off within 20 minutes. Unfortunately, the night before I had installed a new modem, and father in law thought I had wired up something incorrectly. Luckily, he told them, he would get me to ring them back. With this, the caller got quite aggressive & got hung up on. I haven't rung them back & guess what? No problems, nothing cut off.
TOTAL SCAM! About time these lowlife scumbags did something useful with their lives.

Caller: random fella calling himself Albert Johnson

repeated calls from people claiming to be Telstra's technical department saying there is a critical error in the main server.
They were clearly in a call centre given the background noise.
I'm not with Telstra and they are asking me to open my devices and give them information.
I was naturally pretty suspicious and clarified with Telstra who confirmed this was a scam.

Don't fall for this scam from (02) 8007 3407.

The lady with foreign accent said she was from Telstra ringing about slow internet connection. Plenty of voice noise in the background and she was difficult to understand. I told her that Telstra informed me that Telstra would not make such calls. She insisted that she indeed was from Telstra and that I could verify the call by ringing (02) 8007 3407. The number she called from displayed on the Calling Number Display was 02182547879 which is a very strange number combination for Australia, even as mobile number.

Used for Telstra scammers

Not sure if this is a legit phone no
