Why didn't use credit card to pay it?

Hello Holyhead-distric, 

Welcome to the Community page, 

In order to to help you could you give us more information. Did you purchase an account with us at quickbooks but the email address is wrong? If so then your best bet is to cancel it and take out a new account with the correct email address linked to it and get the offer as well.
