Since you have not completed your full notice period, the employer has the right to hold your Full and Final Settlement as well as your Relieving Letter and Experience Letter.
In this case, you can simply request these documents from your employer. If you decide to file a case against your employer for not issuing your full and final settlement, relieving letter, or experience letter, the case will likely be ruled in favor of the employer due to your incomplete notice period as specified in your Appointment Letter.
Therefore, I recommend that you follow up with your employer and politely request the clearance of your full and final settlement along with the issuance of an experience letter.
