If I want to unlike a Twetch, do I get a refund?

You could perhaps transmute the twetch? If you added the right comment over a quote of the twetch. the comment would make it clear you don't like the quote any longer and if its good the first like or two would essentially refund the mistaken like

Clever, you are always two steps ahead on stuff like this.

Not really but thanks. I coincidentally was attempting to use the word "transmute" in a sentence when i logged in 10 minutes ago
