Received 3 more signed letters yesterday evening. Sent them to usual suspects this morning as PDFs in emails. This time I asked for delivery receipts to make sure the emails got through. Got a received receipt from Barbara Forrester at VicRoads. It turns out she is the Office Manager for the CEO's office at VicRoads. Searched the internet for her phone number and gave her a call. She confirmed that she had received my 2 emails and one letter and she promised that someone would ring me on Monday. Hopefully this may be a sign of some progress but with VicRoads recent history of non-activity who knows?
