Didn't leave msg. Suspect scam call

Caller: Telstra (Apparently)

They keep calling about network faults and identifying thems selves from the technical department.
Said they are in Victoria but has the WA Area code.
Suspect scammers?

This number and several very similar ones (ending in 4 or 2 or 7) have been calling constantly for 3 days. Clearly an overseas call centre. Always the same script saying they are "NBN" and they have noticed something wrong with my internet usage. Have reported them

Scammer - Pretending to be NBN upgrading your phone line.

Just hang up on me

Scam

Didn't answer, no message left.

Don't anyone in WA and actually no one knows my mobile number except my close family. It must be a spam

Caller: scammers

State they are from the NBN - Scammers - NBN do not make unsolicited calls. They have been reported.

Know idea.Recorded msg mentions something about a subscription, then call drops out...I've had this on multiple occasions

Didnt leave a message presume its a spam call

Don't know anyone in WA, scammers using different numbers everyday, phone blocked showing up as spam
