Informa Tech Director interview questions

I got an interview scheduled. The recruiter sent me an email to ask if the timing (date & time) were fine, and I replied to confirm. On the day (work day) of the interview, I waited for the call but I did not get any. I decided to drop the recruiter a note, no reply. I also dropped a note to another recruiter from the same company/region/country. I was redirected to the non responsive one. I just hope they give respect to other people's time, this is a reflection of the company's values.
