EV (EValue) Lead Java Developer interview questions

I went for interview at Evalue through consultancy firm. Interview was in 2 parts wherein 1st part is the technical online test which I cleared with very good percentage as displayed after the test and even confirmed by their interviewers and 2nd part was face to face interview which took around 2-2.5 hours. Face to face was again divided into 2 parts wherein initially I had discussion with the Manager/Business person regarding my experience and how I fit in their course of business. they were very positive with my experience and my suitability for the role and forwarded me for technical interview wherein we discussed the test I solved online and then they gave me more technical problems which was to test my OOP and problem solving skills. And I solved all the problems laid in front of me and the interviewers were happy with my performance by the end of it and gave me company tour and told me about benefits. They ensured me that they'll provide my feedback to the recruitment firm within 24 hours. Its been 15 days and on dropping mail to recruiter i got the response that EValue has yet not provided them with the feedback. Highly unprofessional approach towards the candidate who put in their time, efforts and money for appearing in front of them.
