Hung up as soon as I answered

Rang twice in 2 minutes. I called the number back but got a message that the number was disconnected.

Women identified herself as apparently being from Telstra, asked why she would be calling me she said that over the last couple of days they’ve had a lot of reported issues. I know this call is a scam as my phone is under a business plan with six other users and I am not the main contact for the account.
