Hi everyone. I went to the Simply Energy site and found a link to a "Do not contact me" email.
http://www.simplyenergy.com.au/contact-us/dispute-resolution/
or directly:
info @ simplyenergy.com.au
with "Do Not Contact" in the subject line.
Don't forget to include your mobile number in the email (...I nearly did...der...)
I've only just done this myself, so fingers crossed...

Yep, me too. Busy doing something which you stop doing to answer the phone. Imbeciles is what they are. Time wasting is what they do well.!

Terribly desperate people these telemarketers have become. So sad! They once were human.

I think this is the bulk wine sales company Peiroth.

I have had enough people ringing dont leave a message if it is important enough to make the call leave a message

I am sick of people that ring and do not leave a message. I can't be bothered with such imbeciles.
