Service included with purchase

Dear Apple Support Team,

I hope this finds you well. I recently purchased a new iPhone 15 Pro from the Apple Store, and during the activation process, I noticed a prompt offering a free three-month trial of Apple Music. However, at that time, I clicked on “Not Now” as I preferred to complete all the setup steps before activating the trial.

Now, as I try to locate the offer, I am unable to find it. When I open the Music app, I only see a one-month free trial. I would appreciate your assistance in accessing the three-month free trial that was initially offered.

Could you please guide me on how to activate the three-month trial or provide any necessary steps to ensure I can enjoy the extended trial period?

Thank you for your time and assistance.

Best regards
