This product key is no longer valid

I bought a new 1 year Norton 360 platinum. It is supposed to have a 1 year subscription from the moment of activation, however when I entered the product key this message “This product key is no longer valid. Purchase a new product key to help keep yourself protected.” appears. I would like help resolving this issue.

When was purchase? from where?
You’re entering key - where?

Norton 360 Platinum sounds like Amazon?
And was key activated? registered with your Norton account?
What does your Norton account report regarding this key?
Does your Norton account have payment profile?
