This is not an item you can order. You will not be charged. The Personal data update is used to submit any change in your data to UGG. That way your data are secured by SSL. So a virtual "order" is created in order to get UGG a mail that your data have been changed.
If you just enter your Customer Data without "ordering" UGG gets no mail and we do not know that you have updated your data.
Just correct any information like address, Phone, e-mails, credit card, security code, bank data in your Customer Data at the UGG Online Store.
Of corse you can use other ways to submit your data like phone, fax, e-mail, letters.
