It usually happens with certain hosts. You can try to exit Mass Effect 3 and restart, sometimes the credits come back, but not always. That's the only workaround there is at the moment.
Oh, thanks for the link! I was unable to find explanation at the time. Looks like I was a little bit greedy, and greedy pays twice.
Just curios: how many time it takes to get 2400 packs?!! It's insane! I was bored to death after only a dozen or two...
Anyway, this story glitch-packs ended fair: I still got (some) free stuff, as was planned by devs, even if not as much as less greedy. :-)
But with lost money - that still troubles me. I encountered that for the first time in God-knows-how-many games. Is there any statistics? Quick search on "lost credits" not found anything (that's why I started a new thread).
The 2400 packs guy was most likely someone with a macro-controller. Honestly can't believe someone would do this himself. This alone would be punishment enough (There were only max 50 promo-weapons to get anyway...).
I don't know of any statistic. Best way to avoid it is hosting yourself.
