Refund for iTunes Purchase

i was trying to see if i was eligible for an refund to an purchase i made recently by purchasing an song by mistake thinking it was an ringtone. it should be under Bri Babineaux song Love You Forever, i mistakenly purchased the full song thinking it was an ringtone. i would like for my refund of $1.29 plus tax to be refunded back on my bank card. so sorry for this mishap. thank you for your consideration.
