Game won’t load on PC

I’ve spent £90 on a game that worked for about 6 months and all of a sudden stops working completely won’t load and all that comes up on ea is an error on our end I’ve spent over £200 already and now can’t even play the game and have missed some of the good promos that I can’t play would be willing to take a refund for a proportionate amount or atleast and answer on what’s happening. Have already tried everything online and nothing works
