NHTSA Complaint #11558979 — 2022 TESLA MODEL 3

The rear middle seatbelt in my Telsa Model 3 is stuck. Somehow it got stuck behind the middle seat after the seat was put down to put long items in the trunk. Tesla mobile service sent a tech to my house but he alleged intentional misuse - as if me or my family intentionally were playing with a seatbelt and wrapping it around a seat. Furthermore, even if we were to assume intentional misuse was correct I have 2 questions: 1 - why is the top of the seat belt (where the seat belt comes out of the seat) unable to be pulled to create any slack? 2 - why does Telsa need to replace a part if the seatbelt, or seatbelt mechanisms, are not defective? After searching online this seems to be a somewhat common problem with Tesla - especially the Model 3, at least as early as 2021 - both on reddit and Tesla Motor Club forum - this seems to be a recurring problem. How does one know it cannot get stuck while driving or while someone is buckled in and cannot be released or have any slack? This is a major safety issue.
