Marsh Risk Modeler interview questions

Senior Talent Acquisition Consultant called me stating they had emailed me for screening, although I did not receive any emails from them before that. I was telephoned-screened by them the next day and invited to an interview with the hiring manager the week after that. 3 weeks later I still have not received any follow up, I emailed HR and again they told me the had decided not to continue with the hiring process and they had allegedly emailed me weeks earlier, again i did not receive any email from them.
