PC Black screen issue. I would like a refund please

I'm having the widely reported black screen issue on the PC version of the game. For those who don't know When you load the game in full screen mode the picture doesn't display, you just get a black screen. Only way to get round this is to play the game in windowed mode which really sucks.

I only started getting this issue a couple of weeks ago after the latest game update. I update the nvidia game drivers to latest version with clean install but this didn't fix the issue.

I have tried i think all suggested ways to fix this known issue but unfortunately none have worked for me. I don't have the corsair utility app installed. i did have the Corsair link 4 software installed so i uninstalled that and all corsair applications. This didn't resolve the issue.

I have tried the clean boot method into windows, the bug still existed. I have tried repairing the game, updating the game still nothing works so I am left unable to play the game. Windowed mode does work and the game display correctly but i don't want to see my wall paper and windows task bar when I'm playing the game, it detracks from the experience and ruins the immersing feeling that full screen mode offers.

PC specs: Win 10 64 bit

Intel 5820K

Asus X99-M work station

32gb Ram

MSI 980Ti 

I put a ticket on the EA error reporter system stating all the above.

As there appears to be no solution presenting itself i would like to know how i go about requesting a refund and deactivating my game key and removing the game form my origin account.

Please can someone point me in the right direction for EA's official route to begin this process. I'm not prepared to spend £40 on a game that simply doesn't work in this day and age. Its a shame as i was enjoying the game for the month or so it worked properly.
