OMG!! its not just me .... im having rxact same problem & its not the 1st time. It wont find the postcode which IS correct, it will only search NT postcodes & I too keep getting invalid message & it asks for me to choose service, cant do that because its ony letting NT services come up. Ppppppd off!!!! Indeed i am, I hate waiting fo people to send stuff & I hat e being the sende & people having to wait, that irrates me even more .... I sent an email to Click & Send, its same problems that existed months ago & still not fixed. If your going to have a progam available thats is suppose to be "Hassle" free then tweek & and get it sorted!!!! We pay for sacthels but cant use them if we cant complete process .... double grrrr thats my rant .... but probably not the last of it ....
