Redeemed iTunes money disappeared
I have had itunes money for a while sitting in my account, about $5 left, and I went to purchase something and saw that I no longer have money on my account. I redeemed the card a few years ago, but the already redeemed money shouldn't expire. I remember checking my balance a while back too and it was about $3.68. It seemed to have been slowly disappearing day by day. No one else has been on my account. Please help.
