A:AnswerNo catch, Apple just wants you to like it and subscribe to it. Any time I try free subscriptions out I'll set myself a reminder in my phone calendar to alert me to cancel the trial a few days before the trial ends. It's very easy to cancel the trials.
A:AnswerCall customer service if you did not receive the code. I asked if I didn’t receive it was because I didn’t order anything(although I did just buy am apple watch the same week, the offer wasn’t present—-I didn’t tell them this ). They needed to confirm the order number and was able to send me an email with a code.
