renting video on amazon prime video

[JLow]

Cannot rent movie on amazon prime video. Amazon says payment declined and that my amazon prime video payment method is not set up it directs me to settings in amazon. When I go there its says I'm paying through )2 and directs me to O2. When I get to 02 website cannot find any guidance on this. Help anybody

Not sure if you chose Amazon as an Extra when you took out a new contract or upgraded?

All info here Guide: Adding and removing O2 Extras  

Amazon video allows you to watch selected videos for free. Others you do have to rent. No idea why your card would be rejected though. Have you an Amazon account?
