Re: "I bought a new MacBook Air m2 and I when I set up my new MacBook I didn't get apple music 3 months trial and also apple arcade 3 months free? and how should I do to get these services."
Seems you need to redeem the free trial offer(s) using the new Mac.
Note: A free trial needs to be cancelled at least 24 hours before it expires in order to not be charged for the next month ahead, if you do not wish to continue subscribing. The free trial ends immediately when you cancel..
