Accenture India — fake company | worst recruitment process

I am working in sapient. One of my friend in accenture referred my profile in accenture and they interviewed me 5 times and process took almost 3 month. After many stages of process, i got a clearance from document upload team. Hr told me your offer is pending and soon we will be having offer discussion with you and roll out your offer.
But all of sudden, application status changed to "candidature is closed" and when i tried to talk to hr. She replied rudely, i don't know what happened and ask your talent coach. She was my talent coach as per last updated on portal and replied me like this and cut my call. I am not worried about joining accenture, am already in a good position but at least if you wasted your much time in a interview process (2 month) then you have to tell the reason for closure of candidature.
By such status change, now one can't apply on any other open need there. Seeing this kinda thing was very disappointing for me. This incident shows how pathetic is accenture hr team and their recruitment process. I never seen such stupid behavior from any other company in my whole career.
