Sounds like a personal problem that you decided to post to HN for some reason.
When we build apps we need to be aware of "best practices". This includes customer service, feedback within the app when an error occurs, and billing standards. Login issues 4 years into development? Either their framework wasn't properly unit tested or their apps integration to it wasn't.
One thing I should probably have mentioned in my piece and which I'll likely add; despite the tons of email HowAboutWe sends, the only email I didn't get was one confirming my purchase or containing a receipt, although my CC was billed.
