Are you eligible for any dues if the company terminates you for long absence?

Dear Sir,

Please advise me. If the company terminated me, am I eligible for the gratuity?

I went on emergency leave for 15 days on 17 December because my father was sick. After that, he expired on 07 January.

I came back on 4th April. I overstayed 75 days. Even I informed my line manager 2 times on 31 December and 19 January.

Now the company terminated me and took my signature on termination later and the company doesn't accept to give my gratuity.
