My BF1 game key couldn't be redeemed

Amazon says it is being sold by Electronic Arts.

Sure, will do

I'm not sure why you would be directed back to us, the retailer is responsible for a purchase. At best support could verify that the code was indeed already used. 

Amazon "sellers" are either Amazon themselves or 3rd party operators. If one is purporting to be Electronic Arts can you link their page? I checked the US site setting BF1 and I could only find Amazon and some other 3rd party sellers. 

When we sell games directly, we do so through our Origin platform. 

I have contacted amazon again a few hours earlier, and they said the same thing they did before.

I honestly don't know what to do at this point

Can I check what the seller was listed as within Amazon? What Amazon version/region did you buy the game from?

Earlier you mention not being able to get through to support, if this is happening can you can try swapping to a different browser or device, in case there's a local issue. 

Checking on this it looks like there's an account issue that'll prevent you from playing even when you get the code issue resolved, so you'll want to get this cleared up. 

I did try with a different browser and a different device.

It doesn't look like I can find the item. Search is only giving me results for consoles

Same but for me it says code invalid please ea i payed money ffs i want the f*cking game

@HunterOfTheEnd

As has been thoroughly explained, you do not NEED any "key" if you buy from Origin.  Any other seller, if the key is no good, you must challenge the sellers themselves.  No one here, or EA, or Origin, can or will do anything to support a retailer's bad faith. 

Hey @HunterOfTheEnd,

in addition to @Gorath_the_Elder's words, here's a list of trusted retailers, for future reference.

If the code is invalid and you purchased it from a trusted retailer, feel free to reach out to an EA Advisor via phone or chat who should be able to assist you with your issue.
