12 was about the amount of agents I had to speak to as well. Understandably most support agents do not have the tools, or are not trained on how to use them, since BF3 is 12 years old.
Regarding the F2000, I seriously doubt you will be able to get any assistance for that, since the game is even older (15 years!) and since it's being sunset in a few months. You could always try, but it'll take way longer than the M1911, if it's even still possible.
Seems like there are very few people who can still do this at EA Support. I mainly made the original post so that people keep trying and don't get discouraged when so many support agents tell them it's impossible.
Still no success with the F2000. ☹️
