Unfortunately, I don't see the possibility of the site refunding all the spins they owe... It seems impossible to me. But with Freebitcoin, apparently anything is possible, except for someone from their team showing up and giving some explanations.
LOL. You just roasted them with the last line. I understand they are one of the old casinos, and they had a pretty good reputation on the forum. But they have been inactive almost everywhere. I don't remember seeing them anywhere. But I often heard that they still send promotional emails to their customers. I do not see their ads on crypto websites anymore.
There are dozens of complaints in their thread, and they did not even feel to show up and provide some kind of excuse at least. Even if they are unable to fix those issues, they could at least show up and promise to fix those problems in the future.
