how can i file child support ?

hi

im a 24 yr old living in davao city .i need help on how to send a demand letter for the father of my son. his father is from luxembourg europe. we are not married .ive just gave birth last month by cs and his dad is making it hard for me to get child support ,he always get angry if i ask money for his even just for his milk and diaper i need help badly.

beforehe replys sometimes when i send an email to him.but he's just always making an alibi
everytime i ask support,before when i was pregnant he just give me 3-4k a month for check ups only good for aug-dec he promised me he will come when i gave birth but till now he's not here yet..and dont even reply on my emails .

i also want to file for emotional abuse.

any advice will help.

look for family support groups in his country. try also to contact his embassy here.
