Putting my Premium back from downgrading

I made a mistake and downgraded my Premium to basic, a few months ago. My annual premium ends in mid-January and I want to put it back to the way it was. I would like to keep my premium like I never changed it. Is that possible or do I have to pay additional fees to get it back the way I had it?

If you paid for an annual premium, it will remain active for the full year. Your account would downgrade after the year, but I cancelled that for you. It won't downgrade now. Annual account automatically renew, so if that's not the plan, you might want to recancel
