You have posted that:
--“My Last working day was 17 Sep. 2011 with IBM , My manager had given to me on mail that My Last working day is 17 Sep.”
Have you also mentioned your effective date of resignation as 17 Sep. 2011?
If yes there is no ambiguity.
--“But in Exprience letter , it is mentioned 19 Sep. 2011”
It is wrong.
--“they replied , all your processes are closed and we can not change it now as per company policy and process and I had marked mail to HR Head and Sr. managers in CC to resolve this ,”
If the HR personnel have erred they have to correct the errors created by them. Who else will do it?
If company personnel in line management/HR are unwilling then it might be for the reason that they shall be taken to task by their masters. The company might be in the habit to invoking compliance issues against the erring employee. It would go into their personnel file.
But why should you live with any error and adverse implications?
--“I asked to my manager and HR also to correct it”
Did you ask verbally or in writing?
Such matters are deemed to be taken up in writing.
