I never received a response from BA, but at the suggestion of another Ppruner I tried the Executive Club forum on flyertalk.com. I got a response fairly quickly, but saying that she tried but couldn't get my seats back. So I went back to ba.com to select other seats and discovered I had 28BC back on both flights.
So, not sure what happen, but thank you ... thank you ... thank you!
(And thank goodness Mrs ExXB never found out)
