Accenture India — I am complaining about, why my application is closed and blacklist

Address: hyderabad

My candidate id is C9576736. i have completed my online assessment and technical interviews on june 10th and i got a mail that i have cleared technical rounds and next is HR round. next day i got a call to submit all my documents. i have submitted my documents. its being a week i havent got any call back. and i called all my HR's and i dropped multiple mails to HR teams i havent got any reply. Today after calling multiple times, One Hr lifted call and said, "Your candidature is being closes because your backlisted", when i asked why, what is the reason, he said, please check with your HR. without properly intimating what exactly is the issue, how can Accenture blacklist. I have all the proper documents, please recheck, if there is any missing document, i can resubmit them again. but please dont play with others life by blacklisting

i need proper reason why my application is closed?? Please resolve my issue.
