Hi Kumar,
According to you, you have done your part well by sending clear communication about your resignation through mail and on the date on which you need to be relieved. They did not give reply mail to you, but they orally confirmed that you will be relieved as per your mail.
But kindly answer to my following points to have better clarity,
1. Why did not ask your HR people to give confirmation mail through mail? What made you to wait till last date & Cry?
2. You said it was communicated to you manager but let me know who communicated and how it was communicated to him? if they called him/her on phone and informed about your resignation, then no point in asking your manager for the explaination as he may come and say that he was not informed about your resignation.
3. Since you are working closely with your manager, you could have asked about your relieving little earlier. So that, he would have supported you in relieving.
4. 1. Is there any clause on Notice Period Pay mentioned in your appointment letter?
5. Can you please discuss with your HR department that if you can pay notice period amount for rest of the days, they will be ok and relieve you?. They will accept and do so.
If you don't want to pay anything. Then you can take a final call and push off as you wish. You don't have to worry about it, because, they can not stop you as you have a proof for the communication sent on your resignation. Since they did not response, you take a call that's it.
But as Mr.Rohit Said, they may delay in processing for Experience/Relieving Letter or they may even say that experience/relieving letter will not be given to you, but they can not say that they will not process for your F&F and will not settle any dues to be paid to you. Because they have no rights to say Experience / Relieving letter will not be given to you, even after completing 45 days of notice period.
In case if they are saying that they will not process for F&F and they will not settle any dues, even after you accept that you will pay notice amount for rest of the days, then you can tell them that you will take legal call.
To be on safer side, keep your new employer informed on this issue and ensure there will not be any issue with your new employer after relieving from current company.
