awful - no tech support, receipts gone!

I had thought it was an awesome app until I needed to restore my files after phone crash. The app would diligently inform me it was backin up my files every 2 weeks... but to where? I have no idea and I cant restore my years worth of receipts gone! Tech support has not emailed me back after weeks of trying and their website is useless. A waste of money and time and now Ive got to recreate a years worth of tax receipts (if I can!)
