got a new number and 3 times in over 3 days i got calles from this number. even after me saying to take my number off there call list

Why does Telstra allow this to happen they are nuisance calls and always a Private number ,,thats it no more will answer a number that is private anymore.

Answered this number twice and a voice message says goodbye

I took a call from this number, I answered and the reply was automated "Good Bye"
once* you answer, it tries to route the call to a telemarketing agent, who pretends they "called" you.

If there are no agents available, the dialer drops the call, but with the zero cost of VoIP calls, it doesn't stop – it tries to keep the sucker pool full, so agents receive a call the instant they finish one.

energy spam

bloody energy wanting my bill so he can sign me up to a new plan

Rang back 5 seconds later,said number was disconnected
