random hang ups whenever I answer. Annoying, and now blocked.

Actually Michelle that information about the do not call register is not 100% accuarte.There is an exemption where some public interest organisations such as charities can still call you as well as any businesses you have an existing relationship with such as the bank.The below is from the do not call website's FAQ:2. Will registering my number stop all telemarketing calls and marketing faxes?No, registration won't stop all calls and faxes. Some public interest organisations (e.g. charities, political parties and educational institutions) can still call numbers listed on the register. This ensures these organisations can continue to provide valuable services to the community.If you have an existing relationship with a business, it can still contact you, but you can advise them you do not wish to receive telemarketing calls or marketing faxes from them in the future.

What a great website setup - thanks heaps Dan - I received something from Commonwealth last week in regards to income protection insurance so this makes complete sense.FYI - I have just found a website that you can enter your number and telemarketers arent allowed to call you... https://www.donotcall.gov.au/

If you call 1300 305 515 and tell them your number they will stop calling. You will also have to call your bank and tell them your number is private and they cannot give it out for marketing purposes.

I received a call just then from this number but as soon as I said "hello" they hung up.
