Thanks for your replies, your help, and concern.
Something very strange happened.
I was also emailing my travel agent and not getting a response. So I called him. He said he was responding to each and every email I sent (4). I said I had received none. He said he clicked on my From and it went to Outlook.com. That's not my email! How did that happen?
So I emailed the Concierge again and asked that they specifically do not click on my name but to send any reply to my email ___________.com.
I received a reply last night. To the correct email. They said their emails were going to Outlook.com., but I didn't receive them.
So all my requests have been fulfilled. The concierges probably think I'm crazy, but I'm happy now.
Anyone know how/why this happened?
