Your new account will be processed by at least 2 people. First they will establish your account then within a couple of days a different person will load the points.
I have always called the MS phone number and asked the CM to check for our account by searching by SSN. They then gave me our website login info and our member number. I never received any mailed info other than our member ID's which took a few weeks.
If they can't find your info, call back a couple of days later.
