Wipro — Not getting onboarding mail for more than 3 months

I got offer letter on January 24th and joining date on 16th May. Due to my semester exams I postponed my onboarding.After 2 days recruiter's called me and asked what is the reason for postponement and when you will be available. I told them that July month. And she confirmed me that your joining will be in July month and you will receive mail before 15 days. Now July has ended. I didn't receive any updates.what is going on there? ? Wipro team only confirms. If you postponed then after 2 months you get your next joining date. 3 months crossed, no updates? You guys are making fool of freshers...How many families are dependent of them? Why you didn't consider their situation? Why you conducting exams and interviews and all?
