Hang in there! Denied several times, the phone number did the trick for us too. We had a Monday departure also, and everyone was working remotely on Sunday so it took a bit more effort. We got the BD Veritor rapid test on Saturday morning and immediately submitted, and it took until later Sunday afternoon to finally get that nice email with the green header instead of the dreaded red one. Also, as others have pointed out..it seems to work best when you submit each person from their own email address.
