Accenture India — Cancellation of candidature

I am selected for the Association Software Engineering position, cleared all the rounds, and also completed my 45 days pre joining traning, and they have approved all my documents including experience.
I have given 2 mocks also, At the time of 3rd mock i was unable to login, I mailed regarding the issue and got a reply that, my candidature have been closed because I have more than I year of experience, so I am not eligible for the role.
I had clearly mentioned in my resume about my experience and in interview also, I told about my work experience to the interviewer, and on task portal on 11th October 2021, all my documents got approved including experience detail. Now on 15th November they closed my candidature without given me any prior intimation.
After getting my documents approved, I rejected the other offers which I was having.
What should I do not?

Just I am requesting you to reconsider by candidate because my previous experience was of NON-IT and I am fresher for the IT industry.

Request you to please reconsider my candidature, I have dedicatedly invested more than 2 months in traning and other activities for Accenture.

Hope to hear from you .

Thank and Regards,
Prateek Mishra
