I think we all have approached casino first with our grievance Miscoding unlicensed ect ect requested full refund .It would do you well to read all their terms and conditions ,check their licences governing bodies Costa rica licences are basically null and void New licencing laws took effect last year so any site displaying jazz licences are trading illegally with expired licences .I would also read the new gambiling licence laws for Malta, Caracaco as there are rules now casinos must adhere to . But even then Caracaco is still dodgy all back handing and corruption. But things may chance now new laws come in you can also check on the CGC what gambiling sites and companies have licences and when they expire.
You may get same ole speel as we all get .I managed to get a full refund from 1 company but it took a while and had to sign a NDA so can't disclose anything about what site it was .If you get nowhere from sites then approach bank .I have also warned and told sites that I will proceed with chargebacks and will take legal action if no resolution. Due to breach of sensitive data as our cards are supposed to be stored securely and encrypted end to end and they are not they are given to unregulated 3rd party merchants who are unregistered with the FCA .
Hope this helps be persistent ,if no luck then chargeback
