I can see that Ice36 is owned by SkillOnNet Ltd which is a pretty reputable and MGA licensed casino here in Malta. I’ve had accounts with their sister casinos in the past, and had no issues.

Not sure if this is the case, but your documents are probably still processing for the payments team to process your withdrawal at the time of your post. If you’re still facing any issues, instead of Live Chat, you can reach them at [email protected] via email.
Ultimately if you can’t reach an agreement with the Casino, you always have the MGA at your disposal and can lodge a complaint here – https://www.mga.org.mt/player-hub/lodge-a-complaint/
However, please remember you will have to exhaust every option directly with the casino before the regulator will address any concerns.
Let us know how you get on!
