Refund Now!!

Built a higher end rig specifically in anticipation of BF6’ and since install I have spent 20 plus hours attempting to fix this POS game, with no resolution. Works in my console, but now no steam game works on pc due to DXGI or Device Error Hung. 

What are your suggestions on getting a refund, as EA / Dice clearly has no desire to address?

Thanks in advance for any constructive advice.
