I've purchased The 3 Week Diet book and after I paid a received a download link which was not working. I tried many times but wasn't able to download anything. I emailed The 3 Week Diet tons of times with no luck getting a response.
I guess in my case they should have refunded my money or at least they could provide me with a proper link, but it seems like these guys really don't care. They got my money and that's all.
