Zero Help – Mantis Bible Study Review

The support for this app is horrible. Made an in-app purchase through I-Tunes that failed to download. Went through their process in the App to try a restore the purchase and it gave me an error. Tried emailing Mantis using the help email address provided on their website and it came back as undeliverable. Then tried messaging them through their Facebook page and have gotten no reply. Why are they still allowed to sell anything???
