Did you try Cosmotown?
You should read the ToS of each registrar some write it clearly that there is no refund for such cases, some will write that they offer refund.
At the moment Sav looks easier to me, delete a fresh reg domain during 3 or 5 days and get a refund, I forgot how many days exactly, because i did that a long time ago.
And when you get a refund to your Card the bank will take some fees that is why better to think before registering a domain, same thing with other shops like Aliexpress, you get less than what you paid if a refund happen. This is understandable cause any CC transactions cost electricity and resources to perform, no one will do it for free, even bitcoin and other crypto.
P.s. most of times the ToS are same on most registrars that is why to not read all those pages I go to ToS page and search refund words to see faster what is what.
