Get refunded to credit card - Ricardo

Hi all, I am moving out of Switzerland and tried selling a few items on Ricardo. One of the sales was a fluke and the buyer never showed up. I did the whole cancel the sale thing on Ricardo and thought all was fine. However, I just noticed that instead of refunding to the credit card, they gave me Ricardo credit.

Has anyone successfully argued to get their money back? As you imagine, Ricardo credits are worthless since I no longer live in Switzerland.

I now see that their help guide does say you will get the fees back in credits, but this seems awfully anticonsumer. Even the US shies away form such practice.

I've already contacted their customer service, but I've read they are rarely responsive, so also asking here. Should I just do a charge chargeback given I'll never use them again?
