Ventures Level 4 Teacher's Edition 3rd Edition

My school purchased this book for me, but the Amazon description is misleading in that you don't actually gain access to online content by virtue of having purchased the Teacher's Edition. I was in conversation with Cambridge customer service for ~a month and they refused to share an access code with me so that I could use Presentation Plus (one of the main reasons I wanted to use this book) unless I bought the book directly from their website which is absolutely ridiculous.
