I let answering machine pick up this call. As I have had this number call me previously. Claims to be from Telstra Technical Dep. in regards to internet being to slow. No message left, they just hung up once answering machine took over.
As previously with this number when you ring back. Recording tell you to check number as this is not a correct area code For number.

I was out when call came through. No message left, however I believe this was a scam call. I rang number back and recording said this was a disconnected number.
More than likely call I received once home from (03) 5629 3799. This caller said she was from Telstra technical dept. She was calling because my internet wasn’t up to speed. Said if I would co-operate with her, she would fix it.
I said I didn’t think that was a very good idea and hung up
