Sixth pay commission benefits not got

Hi All
My father was an employee of central railway nagpur.
He worked as errector grade 2 in kolkata.but railway
made him permanent as a trkman in nagpur.
He was retired on 3500 pay scale.his total service was
18 years.He got only 1900 rs as a pension,no pass np medical benefits.
In July 2010 He died from  kidney illness in lake of treatement.
But govt didnt provide him any medical facility.
After all He requested many times but govt didnt give his
settlement money according to the sixth pay commission.
Anybody can help me,because We are not provided any
pay commission benefits.
