denied solo parent ID to unmarried, working and studying mother because biologigal father is giving financial support(only) to child

Atty. I applied for solo parent and was denied. di daw ako qualified because my child is getting financial support mula sa tatay. my son is 1 year old.

di na po kami mag karelasyon ng tatay ng bata "estrangement" kung baga for over a year now.pero minsan pag tumatawag po ako nakakapag usapan pa naman kami.at napagkasunduan namin na ako na mangangalaga sa anak ko since di naman kami kasal pero nagpapadala po sya para sa bata. pero all other responsibilities of parenthood I am currently shouldering

I read the Solo Parent Act. and Family Code of Phil "parental responsibility"  
“Solo Parent” – any individual who falls under any of the following categories:
( Unmarried mother/father who has preferred to keep and rear his/her child/children instead of having others care for them or give them up to a welfare institution;

or meron pa po bang ibang criteria sa Act na pwede ko gamin to qualify for solo parent? gusto ko po kasi ma avail ang leave benefits para sa amin ng anak ko. since nagugugol nga po sa pag tatrabaho at pag aaral ang oras ko. nawawalan na ko minsan ng oras para maka bonding baby ko.

i need your feed back.

write a letter to the supervisor of the dswd office.

will it be possible to file a complaint against municipal dwsd social worker for failing to do her job right?

ano po ba pwede kong i file na complaint againts social worker/s who failed no comply to a certain act. and that their non-complaince i find to be maliscious in nature. causing delay sa mga bagay na na dapat na kuha na nakasaad sa provision ng Act.
