If you've ever called support you know you will spend several hours getting transferred around, then sit on the phone with someone who troubleshoots from the perspective of "is the computer on?" and then determines it is fixed, when it is not. They might perhaps say a manager will call you back, but when you call them back they've closed the ticket and you get to start over.

I would never subject a client or coworker I didn't hate to what you call "customer service".

Also, it is a flaw in your programming that there isn't a way to do 1099-misc corrections. Every other 1099 software on the planet does.
