Help on mail recovery service

I am trying to use the ‘Recover sent, deleted, or expired mail’ service to recover mails from the auction house which disappeared after my holiday. The process works fine until I select my character. It stuck on ‘We’re processing your request. Please leave this page open and we’ll update you as soon as we’re done.’ and then times out.

I have tried many times at different hours on different days. All stuck at same place.
What shall I do now?

Have you tried a different browser?

Yes. tried Chrome and Edge. Same issue.

anyone managed to get it fixed?
