Hi Srilatha,
Up to the warning, it is okay. But do not terminate because if you terminate, then you will not be able to recover one month notice pay (recovery of the notice pay can be done if the employee leaves on their own without serving the notice period. In termination, the employer terminates the services).
Therefore, after the warning, serve a notice for the recovery of the notice period.
In the notice, first say:
"You have been absenting yourself without authorization or approval since [mention date]. In this regard, you were sent a warning letter dated [mention date] by registered post to which you did not respond. The same letter was also emailed to you, to which you also did not respond. Therefore, we are left with no alternative but to assume that you have left the services of the company of your own accord without serving the notice period.
We, therefore, serve you notice to deposit a sum of Rs. [mention amount] with the company within 10 days of receiving this letter towards the notice pay which you are liable to pay to the company as per clause [mention clause] of your appointment letter number [mention number] dated [mention date], which is reproduced below for your reference and convenience:
"[mention clause of appointment letter]".
Kindly note that if you fail to deposit the required sum towards the notice pay within the stipulated time, we shall have no alternative but to take legal action against you.
In case the company is forced to take legal action against you, it shall be solely your responsibility (and not the responsibility of the company). Therefore, the legal costs incurred by the company to recover the notice pay from you shall also be recoverable from you."
