Hello Olga and welcome to planDisney! It's so great to see you here today.
I can totally relate to your concerns Olga, because I too have made similar kinds of errors on my own
My Disney Experience account as well. Plus, I really like seeing all my ducks in a neat row, so it really does bug me when I can't easily correct my own mistakes!
Since you've already tried
Updating Details on My Disney Account yourself to correct the small error in your birth yEAR. I do wonder whether now might be the time to speak in person with a knowledgeable Cast Member who will be able to make those updates for you.
It's easy to connect with a Cast Member by dialling the telephone number for
My Disney Experience & MagicBands contained within this handy
Walt Disney World Resort Phone Directory. I feel sure that with just a little faith, trust, and pixie dust that Cast Members will soon have your My Disney Experience account looking all neat and pretty!
Olga, if you should have any further questions at all about an upcoming visit to the magic of Walt Disney World Resort, then please do drop back any time to
me here at planDisney. It's always a pleasure to offer some pixie-dusted assistance wherever I am able.
Have a great Disney day ~ Jane
