Re: Origin download for The Sims 4 is beyond fustrating

When you look at the top right on the Origin website, you'll see "download Origin".
Origin is a client like Steam, only Steam provides a lot more makers games. Origin only provides the games of EA.
I would suggest putting the download on, through Origin and letting it sit while you do something else. 
Maybe even let it run in the night. 

If you really feel you want a refund, feel free to contact EA:
