3. Received joining mail from Accenture on 28th June 2022 with the subject: gear up for 1st day
with a site to confirm my joining. On the portal, I selected to postpone my joining to august 2022 since my college exam and results were pending

4. On 30th June 2022 received mail to upload the offer letter, terms of employment, and self-declaration form with signature. I uploaded all the documents.
Screenshot proof is attached.

5. Since I did not get any reply from Accenture after postponing my joining date I decided to mail on onboarding.doc.[protected]@accenture.com
In the mail, I mentioned that I have selected to postpone my joining date. What to do now?

Screenshot proof is attached.

6. On 8th July 2022 I received mail from Accenture with the subject that I reneged the offer. Mail screenshot is attached for reference.

7. on 8th July I raised a ticked on Accenture my zone.
I got a reply from them on July 11.

I got only single mail on 28th June and 30th June regarding joining and I uploaded the docs and gave my confirmation. But in reply, it is mentioned Accenture did not get any conformation from my side.
I neither got any call or reminder email from Accenture before withdrawing my offer.
I think there is no reason for the rejection of my offer letter. I am interested in the job and just wanted to postpone my joining date as my college exam and results were pending.
