NBA Game time on my Iphone 4

iOS & iPadOS
3 feb i purchased the entire season of the NBA GAME TIME ON MY IPHONE 4, downloaded the APP for 29.95 something to that effect, and tried to play the video of the games. Then i was constantly receiving a box stating that the video was not avalible at this time. Then the games were played and over, still i can not access the video even afterwards. My question, is why can i not view the games, as there being played. One other my service is with TELEKOM here in Germany. On a US installation.
