Poor Service from MFC

Been a year since I had my new car. First car was with mfc always got my statements got my new car year ago and they captured my email address wrong. They keep telling me they updating my email because some thick person can see my name Is Kimberlee but puts my email as imberlee now I dont get statements anymore and when I ask them to rectify it they promise it's been updated. Still to this day dealing with a bunch of clowns in a circus. For MFC thats very poor. What does one do to get your details to be fixed and to receive statements? Join the circus ?
