My Creative Cloud subsubscription auto-renewed but I don't want it, I've cancelled the plan but need a refund to the existing payment method

I had a student discount 12 month subscription to CC, it has just auto-renewed at a crazy amount of money which I cannot afford and don’t want.  I only use AE, which I’ll re-start when I need to use it next.

I cancelled the plan to CC but says I’m paid up until July 2027, I REALLY need that money back ASAP but cannot see a way to request an immediate refund.
