This seems to be common problem and absolutely mind-blowing that it is this difficult for customers to retrieve their account to play your games. I have submitted a few cases but unfortunately don't have the patience of the folks who submitted several.
How the "F" are you going to launch a big game coming up like Battlefield 6 when no chat support is available, people can't self-help their log-in challenges?
If I don't get a reply to this, I'm done playing EA games for life... and it's a shame because I love the Battlefield series.
