Yes scammer pretending to be from Telstra to say your internet will be disconnected for 24 hours. When I said we were not with Telstra he hung up.

Block this number in your contacts if you get a call.

Guy reckoned he was calling from Telstra about my internet. Typical scam patter.

Claimed to be Telstra, reporting some network issues and asked me to do some checks on my modem. I'm not even with Telstra.

Nuisance call

Called, said nothing, hung up. Tried calling back and "we regret to tell you that the number you have called is incomplete". Some timewasting phone scam.
