Where to sell a game download code?

Aright guys. I bought an Xbox one last week and the bundle came with a download code for Fifa 17. I hate football games so was going to sell it. However. I've been warned by 2 different people not to do this on eBay as it more than likely I'll get scammed for it. Seemingly people receive the code then use it then contact eBay and claim it never worked in the first place...

Is there any gaming forums or anywhere else you would recommend to sell it?

Facebook selling pages, cash on collection only.

Never even crossed my mind that. Thank you.
