Well, the process for support fails.
We handle a decent volume and have been a merchant for over 8 years. We can't even get an account manager to handle specific issues.
90% of requests are met with a subtle RTFM!
If you ask specific questions, these are avoided.
An open ticket is bounced from person to person. No two people seem to touch the same issue.
If you try specific chat support, and you ask technical questions, you'd expect some knowledge. Instead, most agents put you on hold and go over documentation, only to come back and say they've escalated this to a ticket.
Then the ticket comes back with more links to documentation, never answering the question.
The only way to make progress, answers and some human treatment is by jumping from connection to connection on Linkedin, trying to get an intro to someone inside.
Or of course, getting lucky with an HN post.
