Accenture India — Regarding problem faced in hiring process

Hello, Good Afternoon.
I am Mayank Bhatnagar (candidate id: 956908). My final interview for the selection procedure in Accenture was held on 18th May, 2021. And on next day (19th May) I received an email which stated that my application won't be considered further as I have applied for the same in past 6 months, which is completely untrue. I am in the final year of B.Tech and this was the first time I had applied for accenture and I will be graduating in 2021 later this year. Before this, I had never applied for any profile in accenture nor have I appeared in any of the assesments.
I mistakenly chose 2020 as my passout year while applying but then after several days I reapplied using the 2021 link and it even displayed the message that 'Your application has been updated'. So, I did not get to know that there was an error but now I have realized what must have happened.
I was really looking forward to work in accenture and I think there must have occurred some problem regarding my passout year in the applicqtion. I have successfully participated in the aptitude and coding assessment, communication assesment and in the interview as well.
I was expecting a positive reply but there must have been some error. I request you to please help me and do the needful. I'm sending the snapshot of the email for reference.
Thankyou
