Native Communities interview questions

I had a screening phone call for a Leasing Administrator role at Leeds and from this an interview was arranged. The day before the interview it was then rearranged for the following week which I understand circumstances occur. However, that Friday I received an email at 4pm (1-1.5 hours before the end of the working week) to ask if I was still attending the interview the next week. It was my final day at work so I was very busy however, I still managed to reply 2 hours later. I then received an email first thing Monday morning to advise 'Thanks, but we can no longer facilitate this interview as it was not confirmed and we'll be in touch with dates in due course.' It has now been 2 weeks and I've not received any rescheduled date and the job opening stayed open the whole time. I had the experience and a qualification in property, however, they've not had the professionalism to advise me why they no longer wish to proceed with my application.
