Called my number, as I answered it disconnected - believe it to be spam with robo-calling, then a Indian/human will attempt to call again on a number that they believe is "active" at 5.45pm. Blocked!

Caller: Some Indian call centre

Said can offer better personal internet rates - would not identify themselves -
blind call as called a work/business allocated phone

I rang once this number (03) 8400 6313and got disconnected
