Tata Consultancy Services — Cleared all rounds of interview, got the salary breakup but got a reject email from HR

Recently I cleared all rounds of interviews with TCS and I got salary breakup with X amount CTC. Then I sent an email that I am looking for Y amount as CTC. Then again I got revised salary breakup for Y amount on the same day and I have accepted for this on the same day.

And after few days I got an email from HR that they can't proceed with my profile without having any discussion with me as I am asking for high CTC .

I tried to call HR multiple times but there is no response to my calls neither emails. I would request you to please look into this matter. If HR thinks that Y amount is high CTC, I was expecting they call me back and ask if I am ok with initial breatkup for X amount but they didnt.
