My parents want me to change school but i don't want to?

So my parents want me to change school cause they don't like my headmaster! I know some girls from the other school and they're not like me at all! I really don't want to go to this school, I love my current school I have lots of friends and everything is fine!! My parents didn't even asked if i wanted to go to the other school they applied without my agreement and they told me I was gonna go even if I didn't want to !! What can i do??? Please help me!!
