Free 6 months Apple Music

It mentions on Apple Music official website that purchasing any new iPhone is eligible to get 6 months Apple Music for free,

I purchased 5 days ago an iPhone 14 Pro Max and didn't get those free months !

I purchased yesterday Airpods pro 2, and i got 6 months,

I am supposed to get 12 months in total !

Why the iPhone one's are missing ! and how can i get them ?
