Renewal of subscription

I today renewed my security software and obtained a confirmation email. When I logged into norton I had a message saying I need to provide the serial number which was provided in my confirmation email. I can't see any serial number I have the product code, I have the confirmation number but no serial number. The note also said that I had used the wrong password the only password used was the one I used to log on so how could I use the wrong password? I trid live chat 24 minute wait, then I rand and was told long delays - I can't believe that it would be so difficult to do on online transaction with norton so can anyone provide a simple solution without me having to get onto chat or on the phone. Should I just get onto my credit provide and cancel the transaction?
