Accenture India — Candidature suddenly closed after clearing all the rounds in Accenture

My candidate id is C11736054.

I received a call to get interviewed at Accenture on 10th Feb 2023. It was communicated by HR that After successful completion of digital interview (online test) One more technical interview would be conducted.

I successfully cleared the digital interview after which I received confirmation mail and call from the HR that my 1st round has been cleared and 2nd round of Technical interview has been scheduled.

I successfully cleared the technical round on 20th Feb 2021. After clearing all the interview rounds I received a confirmation mail and call from the HR stating that I need to upload the documents as the next step of the hiring process.
I even received one mail stating that they are accepting my candidature.
After uploading the documents suddenly I got a pop error message on the portal that my candidature is closed .
I didn’t receive any communication or mail regarding my candidature closure neither from HR nor from Accenture team.
I don’t understand what went wrong as I successfully cleared all the rounds and even CTC discussion was carried out with the HR.

This is very disheartening that big organizations like Accenture have loopholes in their recruitment process and the candidate has to face the repercussions of the mistakes done by their hiring team.

It is totally wastage of time and energy of the candidate who took the effort to clear all the rounds and still offer letter was rolled out neither any communication happened.

Please provide the resolution on the same.
