I doubt it works just like that. If you do that you'll have to file for a claim, which will then be investigated by your bank or credit issuer. There's some procedures around what you can and cannot claim for and more things that need to happen according to the Fair Credit Billing Act (in the US). Since you've already taken possession of the good and used it I'm not sure you'll get much out of it though I have no idea how this would even work/apply to digital works.
And I doubt they'll let you go back years.
