The problem was that I scanned the document and the software cropped the edges, and the invoice was actually spanking clean and uncressed. So they thought it could be a PDF export, and not a document scan. It did look too perfect
Scan it "badly", slightly tilted, showing the edges, crumble the paper a bit so its obvious its paper and not digital export PDF. In the end what I did was actually take a picture on my phone (You could see bit of the table on the edges) and saved it as PDF and it went through fine.
GREAT TIP! I will use this for future reference if decided to go the BTCitcoin client route. I just purchased 4rm LocalBitCoins.com
