can't delete my account and it keeps reactivating my facebook!

[rimmsy]

I deleted my facebook and made a new one... but then when i signed into spotify it reactivated me! 
so i deleted the app from my profile, deactivated again. but it carried on, i tried to link my new facebook with my spotify leahrimmsy, but it wouldn't let me, apparently i'm connected to an account "rimmsy" which i dont remember creating
is it possible for me to delete "rimmsy" so that i can then connect my current facebook with "leahrimmsy"??  It's really frustrating!
