Apple Music 6 months free with new device

Hello,

i bought an iphone 13 on february 25 and was supposed to get 6 months of free apple music. Now I am not offered this and would just have to pay € 10.99 p.m. Last time I subscribed to apple music was 10/19/22. Can you help me. I would like those 6 months of free music on my new iphone 13.

with kind regards,
Quirien
