Depending on where you purchased it from, you could still pursue a refund. Steam is pretty rigid nowadays in their refund policy, both in regards to time played and restricting you to a 14 day window. Xbox and Amazon are more receptive to extenuating circumstances, but you can't go through the automated system you have to actually talk to support.
Last year when CFB 25 released broken and missing a key feature I tried to make it work. Then like 20 hours in I got a bug in setting my schedule up that had one team playing 2 teams in the same week and that was the last straw. I called Xbox support and explained the issue and they were able to grant me a 1 time exception to their normal refund policy.
With Amazon, you can refund 1 digital item every 12 months, just again you have to talk to someone through a support call, you can't go through the standard request refund link on your orders page.
EDIT: I should add, if you decide to pursue this, make sure you tell them that EA changed Portal mode which is a core feature of the game, and made it into something that constitutes false advertising. This is not the game you purchased, this is not the game any of us purchased or were promised.
Got mine through EA App... prolly gonna tell me I played too many hours. Then I'll have to do a chargeback.
