"Computers Don't Argue" by Gordon Dickson. Guy gets shipped the wrong book by a book club, tries to return it, gets sent to a collections agency, and things spiral completely out of control from there. It's lived rent-free in my head since I read it years ago. (apologies for the mobile-unfriendly format, this is the only source I know for this story) https://www.atariarchives.org/bcc2/showpage.php?page=133

"Unauthorized Bread" by Cory Doctorow is a more up-to-date discussion of the same kind of power dynamics though. https://arstechnica.com/gaming/2020/01/unauthorized-bread-a-near-future-tale-of-refugees-and-sinister-iot-appliances/
