I have a credit card that I was being billed for in the mail.  They convinced me to go billness and pay on line.  I agreed.  They are supposed to notify you when a payment is due by e-mail.  They didn't.  As a consequence, they reported a 30-day late to the credit bureau.  We are supposed to settle on a house in a few days and I am afraid that this report will keep us from getting the house as my credit was medium.  Is there anything I can do about the report and about discussing this with my mortgage company?
