I bought a $20 iTunes gift card and redeemed it yesterday specifically to keep my Apple Music going. (I turned off auto-renewal to avoid a charge in case I didn't like AM anymore). I got the card 20% to save money. All was well until I signed up and immediately noticed my bank got hit and my iTunes Balance went from $20.00 to $5.01. The mistake is still not corrected and I read a few places you could pay for Apple Music through your iTunes balance. Can anyone point me in the right direction to fix this?
