As I wrote in my first post on this subject: "my (Silver/Sapphire) BAEC number". The same one I've had in my EF account for the past couple of years.
If that's not enough for you to troubleshoot the issue, I'm sorry. But if no one else has encountered the same problem then it isn't important anyway.
As you have deleted it from your account, we have no idea what the number is, we also don't know who you are and therefore don't know what account to look at anyway. Something obviously changed and we would like to figure out what that is.
It's not required to know who else may or may not have had the problem, if one person encountered it, then we want to ensure that no one does if it's fixable.
Your fix is not really a fix as you should have your BAEC number on you EF account to ensure you see the correct BA seat map. If we didn't think it was important, we wouldn't have asked for more information.
Either way, in the time it's taken you to make these posts, you could have just simply emailed us the information we asked for, that would have been very helpful.
