I have been trying to register the warranty on a vacuum cleaner for over a week now. Every day I fill out the long-ass form and submit, but the “service is unavailable; try back later”.
Oh not to mention UPS and inability to enter entry code to their system as they did not pass my phone number or email to them. I did have tracking number, but that clearly is not enough when you can no clearly contact customer. So only option to give the code to them that was to call them...
Like utterly broken flows. Often it feels that no one considers the extremely common corner cases.
