Called twice and never leaves a message

I called the number back; there was a pre-recorded message saying thank you for calling back, our call was about a local fundraising initiative. Very odd, as you would expect they would say which fund raising initiative, charity, or organisation it was to support.

rang twice no message left

(02) 8524 5915
(02) 8524 5929

At first I thought (02) 8524 5929 was a regular person trying to call me while I was out and leaving no VM. Now a second similar number (02) 8524 5915 has started calling me with the same MO and the penny has now dropped. This is not a regular person but a spammer call centre whose ph numbers are now in my "list".

ho ho ho...

This is a company that tries to get you to donate to numerous 'charities'/foundations, etc. They pester, push and annoy.

i have had repeated missed calls from this number on both landline and mobile.

so how, or who do you report this to.
