I am sure that their representatives will read everything anyway. Moreover, I sent them a link to the topic in the chat. I am simply surprised by their indifferent attitude and how they communicate with customers. Such companies that have the slightest respect for customers should not be in the top.
Why not give it a try though?
I mean they represent the company here, and they have been in this community for so long that they know that they need to respond to everyone's complains, issues and accusations. It's a cutthroat business though, so they might be busy at times and may not attend to their customers in a flash. For sure you have experience that in real life as well.
Anyhow, not siding with anyone, but Rollbit might have reasons for holding your funds.
