I have this problem as well, mostly because of my first name. My name is Michele...ONE L! And no matter how many times I tell people this it never fails that someone will add that extra letter so when I try to reschedule an appt, refill a Rx or whatever they can't find me....so I understand completely. You are not alone.....

Most recent problem was trying to convinve them to change my work phone number in their system....the number they had was 2 offices ago! And I have tried probaably 5 times in the past 6 months to get it changed....
