Accenture India — Offer letter accepted, but received a mail that I haven't responded

Hello,

I'm Pooja S P. I had got the Offer Letter from Accenture in the month of May 2022 and my candidature id:C10961317. Post the acceptance I received a mail in July about the onboarding but now I have received saying "We noticed, your offer letter was released and there has been no response from your end despite multiple reminders." I have received this even though I had accepted the offer letter as soon as I had received.

I've raised tickets and yet no response so far. I have been waiting for the date of joining all this time and I received this all of a sudden. It would be really great if this gets resolved.
