Very very frustrated and disappointed

I love the idea of this app. It has everything I want in a diary app- folders, tags, easy to customize. I use kindle fire a lot but iPhone even more. So after long time thinking about it I decided to purchase pro version for its benefits- supposed ease of syncing between devices and online, saving my diary in pdf or text format, in other words access to everything I write on computer, tablet, and phone. So I went ahead and paid $3.99. For three days since every time I went on my kindle fire Diaro it kept telling me I have to purchase pro version again. I kept writing developers with no response at first, and then very limited unhelpful answers. Finally after sending them a receipt for purchase they updated my app on kindle as well as web version to pro. But now I cant sync data between kindle iPhone and web. After I backed up my most used diaro I went to web site and tried to import it from Dropbox only to keep getting messages that the file is corrupted. Again, no response from developers after three days. I have a feeling that unless I email each entry I made to myself and it will take 100 + emails, I wont be able to save 2 years worth of diary. And of course they are not willing to refund. So paying for pro ended up being a waste of money and a headache too. I will have to go dispute this charge with my credit card. Sad and angry about all of this. Dont waste money for a pro version and if you like free version, just remember to email your entries to yourself and save it on computer. But then the app is not very useful to begin with. May as well use free note taking app to journal.
