Can PIL be filed to take an order from court to free birds?

I am a law student and i want to know about the scenario's legal point of view. SCENARIO:- A party was selling caged parrots (my question its legal or illegal to sell them? Publically or privately) I felt pitied on the plight of parrots so i thought to went on and purchase one cage With 10 parrots and free them. I asked the party the price of the cage (which included 10 parrots) they said 250₹ i said ok and i told them m gonna pay them n free the birds there so they help me acc. freeing the birds there at the stall one by one i freed them n afterwards when i was gonna pay them 250₹ they breached the earlier conversation and told me to pay 2500₹ (I paid them) What should i have done legally? And according to legal actions? I shouldn't have paid them a single penny n freed all the animals of the stall N they couldn't take any action against me because it's they who's commiting a crime and i m in the interest of justice? Or Should i file a PIL n take order frm court to free birds?
