Good luck with that, they don't care about millions of other disappointed, cheated & ignored customers so why should they care about 1 more?
This is what happens when we begin referring to "people" as "corporations" or "companies" (EA, Dice, etc) instead of using their real names. They hide behind the veil of the "machine" and do not suffer, so then why should they care?...Guess what?....they don't.
I'm sorry for your misfortune with these people...I have had my own, albeit for a different reason altogether. Moving on to other games who's management is more responsive to it's customers is the best way forward.
Stop supporting/spending money with these corporate giants who don't respond or care. You must take away their power to control you.
