Friend scammed me (Minor) of $150 CA for a bat dragon

I have an irl friend and she got a bat dragon. We had a sleepover and talked and she said she’d sell it to me. After going back and forth we landed on $150 dollars. Three YEARS of birthday money. I love with my mom and we struggle with rent occasionally so it was a LOT of money for me. I gave her the money at school and.. she just never gave me the bat dragon. Asked her on Roblox for it and she just laughed and said she’d she hates me and said I ‘scammed’ her by trying to get the bat dragon for so ‘cheap’ (Her parents both make triple figures) I told my mom but my mom doesn’t have her moms number. The school can’t do anything for it and my ‘friend’ hasn’t been at school for a week. I am so fucking mad at myself because that was THREE YEARS of Christmas money I tried to spend on a DIGITAL PET and I still don’t have a bat dragon.

Don’t know what flare to use, technically trade related
