Dear Azim ji,
In addition to my earlier comments, I would like to give some more comments / my views, point-wise as under which may help you to decide your case.
If it is agreed by both the parties no salary in lieu of short notice by either side, the employer can insist no salary in lieu of short notice.
In case management is not giving acknowledgment receipt, one should send the communication by Register AD Post, asap.
Now time has gone. You should come on record of the company the fact of submitting the letter but not giving the acknowledge receipt, by written communication to higher management.
Any clause in appointment letter or in any any agreement is agreed by both the parties by writing and signing. So change in it should be in writing and singing by both the parties. Mere email communication of change is not enough.
Comments are already given above.
