I was permanently banned on Madden for unknown reasons

Hello OGBryce23​,

if your account was banned, you will have to create a dispute with Support - replies to these are not instantaneous, but will take a few days as the account and the ban will be checked.  We can't help with bans here in the forum as we don't have access to account information.

If you gave your cousin your PlayStation and access to your account during your time away, he most likely did something that was against the user agreement and caused the ban. You can check your ban history to see what kind of ban it is and what reason is given. If you received a franchise ban (so the kind that spans across all titles of a franchise) then yes, you won't be able to play Madden 26. In that case, if the dispute is denied, it's probably best for you to try and refund the game.
