Unprofessional & Rude HR

I was interviewed for a new role at Afrocentric group, HR promised to call me back after 2 weeks with feedback but they never did. I find this unprofessional & rude.

I have sent them emails, and tried calling but there's response. What frustrates me is that I had to spend thousands of Rands on traveling to get to the interview venue (company offices) as it was in a different province. The least they could do is justify my interview with some feedback, whether positive or negative.

The worst part is that this kind of behavior is happening to me for the second time, maybe it's a new trend where corporate organizations interview candidates and then ghost them immediately after that with no feedback whatsoever.
