You can't call anyone at these new companies.
As an S3 customer for web hosting, I couldn’t understand why I was paying 10 cents a month for EC2 charges since I don’t use it. They just refunded me an entire month, but I really wanted to know what was happening!
It's not that I think Amazon is wonderful, I just don't think they're worse than any other giant corporation I've dealt with. Which is why I don't understand jdsully's comment.
Having a first-tier CSR click a dashboard button costs them the 10 cents per month plus 25 cents of labour to pay the guy to read the complaint, find the button, and press it.
Opening a ticket for a well-paid engineer to actually dissect the billing system and figure out where the 10 cent charge comes from, develop a fix, push it through validation and deploy it, probably costs $300.
Though i’d Estimate a fix costs at least 10x $300, if not 100-1000x.
Even then they were non-committal about fixing it despite the person making multiple fraudulent purchases.
With AT&T I tried for over a month to get internet installed and after hours of phone calls and them telling me a technician was coming they eventually revealed the billing department had flagged us and wanted a larger deposit for some reason. The two systems seemed totally separate.
Companies don't have to be feudalism in microcosm by definition, it just so happens that aristocratic ownership tends towards oligarchic governance.
