rings every day, sometimes up to 3 times

I'm with Optus and they called me

Said they were wall stock intsp using Telstra. Very hard to understand but they keep calling after I said no thanks. Barred

I called back number (03) 8640 9719 just kept on ringing no one answered the call and never got any voice mail.

Who the ???????? is IFTelecom 3 calls in one day and i have been with Telstra for 60 plus years

Just another nuisance call close to Christmas.

First call said IF Telecom. Home phone and internet deals. Accepted no good for me. But the next day, 2 calls, I answered and said again Hello, after 20 something seconds they hung up.
