Ration Card — Add name in ration card

Address:

Chennai, Tamil Nadu, 600083

I wanted to add my 4 years old grand daughter's name, approached t. nagar office at valluvarkottam, the officer said said they can't add because the child's father's not in the card. i explained that father's ration card is in nagpur and is unable to transfer due to family problems. child's mother name already in the same, but officer refused to add, please advice is there anyway to add,
