Called every day on Optus mobile, does not leave voicemail and hangs up when you answer

Called, no voice mail left. Been calling every day.

getting rung everyday on my optus mobile... i will be ignoring it in future... annoying

They call me so much I just answer and leave the phone on mute. The she asked "Allison do you want me to disconnect your number" haha. GO AWAY. Its Optus calling to see if you want a range of bullsh*t services.

Calling everyday on Optus mobile

Seems to be an optus things calling so damn much atleast once a day

Called me and no voicemail left.

They told me they are calling on behalf of Optus.
As they have called repeatedly I thanked this lady for not hanging up as soon as I picked up and the lady apologised for disturbing me.
