Very shady how they "Upgrade You" – WritePDF for iPhone Review

I was using the free app which was a trial. When I tried to open a PDF from online it sent it to this app. My trail period was up. Instead of this app showing me how much the upgrade would cost it sent me through questions then told me I was upgraded. It was very shady how it upgraded me and took money out of my account and I still don't know how much it just cost me! I'm trying to figure it out. Seriously, be up front with business practices. I probably would have purchased the app anyway but very shady how they sneak the in app purchase in you.
