I think you will only get an offer if you ask, otherwise, your plan keeps going on, just out of contract.

I got a discount to make my plan the same as the one available on-site. They didn't change it, just gave a 12-month discount. After this, it goes back to the previous price. So I will wait - I have their confirmation as a To Do item on my Outlook with a date just before the contract expires so I know to see what's happening then.
