Ghosting a candidate after a physical onsite is honestly extremely disrespectful

I did a physical onsite recently where they asked me to travel to their office, about 1.5 hours each way. The interviewers were nice and the interviews went pretty well, so I was hoping to hear back from them. The opposite happened. It has been two weeks since the onsite and I have not heard anything.
The recruiter was very polite before the onsite, but after it they completely stopped responding.

I had to take a day off work and make arrangements in my personal life, and the company cannot even bother to send a rejection email? I have never had a job search this difficult before.
