Apple TV+ promotion terms

How are people interpreting this in the Apple TV+ promo terms? Is it essentially saying you can only take advantage of a promo once forever for a given Apple ID? Or only one offer at a time?

“Only one offer per Apple ID and only one offer per family if you're part of a Family Sharing group, regardless of the number of devices you or your family purchases.”

I ask the question because I had the AppleTV+ promo with a MacBook purchase. After that was over I subscribed to AppleTV+ for about six months and then bought a new Apple TV which was eligible for another year of AppleTV+ if it was registered before July 1. I registered it and the 1 year promo appeared in my subscription but when my regular monthly subscription expired the promo dropped as well.

Contacted Apple support and they said I was not eligible for the AppleTV+ promo because I had already received a promo on my Apple ID previously even though that promo was completed.

This is certainly not clear from the terms as it doesn’t mention anything about prior promotions just that if you can only have one device within a family with the promo.

Anyone else have a similar experience? Any recourse here?
