Lost Apple Music subscription after Apple One trial cancellation

Hello! Two months ago, I bought a paid 3-month subscription of Apple Music which was supposed to renew this October. However, I recently tried the Apple One free trial to see what it had to offer and if it was actually worth buying but after cancelling it, I lost my one remaining month of Apple Music. I was well aware that after cancelling the Apple One trial, everything would disappear but I wasn't expecting Apple Music too because I actually ticked the box to keep it and it was saying that I had to pay in order to do so. Since I already paid for that month, could anyone please help me get my remaining month back? Any help would be appreciated. Thanks in advance!
