Employer not accepting "BUY OUT OPTION" during notice period

Hi

I am currently serving notice period in an IT company and requested for an early release. My official notice period is 60 days and I am willing to serve 30 days and pay the remaining 30 days cost.

The following is mentioned in the appointment letter.

You will be on probation for 120 days from the date of your joining, which can be
extended up to another 60 days in certain cases. Being a growth-oriented company there
will be a performance review at the end of the probation period. On your successful
completion of the probation period as described above, your employment with the
company will be confirmed.
During the period of probation, services could be terminated from either side by giving
30 days of written notice. After confirmation, in the event of your resignation or
termination of services, either side will have to give a notice of 60 Days or payment of
60 Days gross salary in lieu of such notice. In the event of resignation, your dues and
final settlement would be credited to your bank account held for Ivy Salary on the last
working day of the following month along with payroll. If you have any Annual Leave
balance, it will be encased in the settlement.
During your employment with the Company, your terms of employment will be governed
by the policies and rules of the Company framed from time to time.
These rules will cover
Provident Fund, Leave Travel Assistance, Medical, Indiscipline, Misconduct or any other
matter pertaining to company policies and rules.


Should I serve my notice period completely or am I eligible to pay the amount for one month and leave.

My manager is ghosting me daily.

please advice!!!
