So today I contacted someone at Origin help again and this time with great succes!
Some guy called Shudham finally helped me out, the game launched after a reload and I got a 15% discount on my next Origin purchase, which I'm quite happy with. This doesn't quite compensate for the frustration over this issue of the last few days but it's at least a nice offering.
Case closed for me, hopefully you guys will get helped too!
