A large amount of calls from this number after I started an internet check test allegedly from Telstra from a different number but they want to access your computers config. I terminated that call. Warnings are on the other number for scammers.

Caller: Telstra (but not really)

Someone phoning to tell me my telstra account is soon to be disconnected... i don't have a telstra account. Spam or scam! Avoid.

phone rang once then hung up.

Rings but doesn't leave a message.
Assume a telemarketer or scam

Very annoying as it happens often

Caller: Man saying he was from Telstra

Foreign speaking man wanting me to go to my computer to check notifications Told him no this is a scam and he hung up.

Supposedly from Telstra about my internet service, I’m not getting the proper service on my home internet service for the account in my name, I said “oh really, that’s pretty funny considering it’s in my husbands name, bye”

Called claimed to be from telecommunication company trying to fix an internet connection problem. Area code 03 calling to area 02 to fix local internet problem. Doesn't smell right.

Caller: Fake nbn from Telstra

Indian busy call center,
Asked me to do an internet speed test from my pc because my server wasn't working properly.

Caller: Telstra

Got a phone call saying that I have reported for slow internet asking for more details for the household, where I don’t even use Telstra.

Caller: Scammer

Got a call to my number claiming to be from NBN - said my internet service was reported as dropping out and he was going to help me fix it. I don’t have NBN and the call was from an Indian (sounding) very busy/noisy call centre. Hung up on them.

Definitely a scam
