Ingram Micro SAP Test Analyst interview questions

I got call from one consultancy for SAP Test Analyst opening.There was five rounds 1.Telephonic 2.US Client round 3.Skype Round 4, Interview with MD 5.HR Rounds .I submitted my document as well as and salary negotiation was completed and they offered me very less hike as per market standard but I accepted offer and they told me that I will get offer letter in upcoming two weeks.I spent my lot of time to given interview and cleared all rounds but Ingram micro mumbai based location recruiter is not less than fraudulent.They was just making time pass and wasting time of candidate.They don't have professionalism and believe in making fool to candidate .I get to know from consultant they have been hired person at place of mine. this is really very disappointing for me and as well as showing image/reputation of company finally I didn't get offer any offer letter. I would like to suggestion to other candidate that don't rely on this company
