Welcome to the forum. Sounds like the cancellation may not have gone through properly and the pass is still active.
Regardung a refund, best to try talking to live chat, explaining the situation and seeing if they can do anything for you. To get there go to the following help page

After you've spoken to live chat don't forget to pop onto your My Account > My Passes and double check all passes are cancelled. I would also recommend enabling your Payment PIN in your account,
