Oasis Collections interview questions

I was scheduled for an interview three times. Once due to technical errors. Second time , I was waiting for six minutes for the interviewer to show up even though I was on holiday myself and had the decency to organise myself. Third time, I was waiting for fifteen minutes for the interviewer. As she did not show up, I gave her a message to which I got a pathetic response claiming she was "too busy". This is the most unprofessional company I have ever dealt with and the lack of communication is appalling. I was told that I would be rescheduled again and have not received a single email or text afterwards.
