Is it possible that the third card was your card that was replaced with one of the other two cards (either expired or for security reasons)? In that case, AMEX should be able to find that refund and apply that to your current card - happened to me with Chase once.

I emailed UA Refunds asking for this information and UA ignored the request and replied with the same information as they had previously, the last four digits. I emailed again and they ignored that message entirely. A third email has similarly been ignored.
Amex has opened a dispute but if United refuses to say where they sent my $3,200 it's not clear how Amex is going to be find it.
I've had some real head shakers with UA over the years but this one is in a class by itself. Anybody have a suggestion what to do next?
