Unable to claim TL50 heavy blaster Battlefront II

I have run into the same exact issue on Playstation 4, not sure what platform you're using however. The offered solution they have given you isn't correct, I followed it and it just brings me around in circles. Classic EA. As for right now I've tried a lot of different methods to be able to claim this weapon but for the time being nothing has worked, and EA doesn't seem like they will fix it after this long. Sucks, but is what it is and hopefully it will resolve itself after some time, but quite frankly, I think we are just going to have to deal. :/
