Renewal dates

My old subscription was due to expire so I purchased an upgrade disc and used the code to renew my subscription.  It didn't go well. but that's another story.  Now it is all working but I find that my new subscription date started from the date when I renewed it and not from the date when the old one was due to expire.  This means I have lost nearly a month of paid for cover and am most dis-chuffed.

 

Is there an explanation or a fix for this. or is the last year I ever use Norton?

 

And how irritating is Captcha just for a forum post?

 

Not looking good for Norton.
