I called back number (02) 9165 4918 reached voice mail for a charity company but did not say the name.

Calls a lot and doesn't leave a message. I called back and there is a recording stating that the call originated from here (doesn't specify a company?), and that it would likely be on behalf of a charity you are supporting or might like to support (also unspecified) also gives an email address to email if you would like to write a request to stop calls but it is a hard to hear, so doesn't really help if you want to be taken off the call list!!!
