am trying to give corrected billing info for Outlook but microsoft is not sending code so that I can get into my account. I guess they don’t want my money. can someone help?

they sent an email saying they could not complete the credit card transaction saying they had a bad acct. number.  Said I needed to access my account billing info or my account payment info and provide a new number.  am trying to do that but they won't send the expletive code so that I can take care of this.  does anyone at microsoft want my money?
