Haha this happened to me. Got a call to a job, went and had a look but it was ok on arrival. Then had another call a hour later that said the lift is still out, which I said was ok when I checked it so again I went and it was still running. I rang back and the call centre called the client, which she said she was standing in front of the lift which was still down. I then twigged that they have got the address wrong and said are you sure its the Melbourne address? silence then ah no actually Dandenong hence the confusion!! Same address wrong suburb!
