Caller: saying from NBN

Kept ringing my TA business so much, other customers were unable to order because the landline was busy! very rude and annoying person. I politely said I am sorry we are currently busy can you ring back another time. Kept on ringing my business for 5mins straight 10x so we had to keep picking up thinking it was a TA order

Asians calling another bloody scam now they call from Sydney, Brisbane and Melbourne and the assas from scam watch say they cant shut them down same as all these 19 numbers that charge you for calls you never made

i have not requested information from this number if they can not show the decency to leave a message i do not reply

I called back number (02) 8317 1351 rang 5 times then goes to busy tone.
