Its ok to complain if you have a valid reason to do so and if you think the terms and conditions are not fair for the side of the gamblers. If there’s a changes and gamblers didn’t agree on this, I think the site should address this properly and answer every queries, this can assure you that the gamblers will stay on a specific site to play. Roobet on the other hand should communicate well to the gamblers especially if they need answers from the team.
I saw a lot of complain recently on Roobet and some of them are still left unaddressed, though it just look like a haters post and maybe the best way to solve the problem is to communicate directly with the site support. Gamblers are usually restricted for some valid reason and the site will always play by the books, so better to understand the terms before you gamble, the site has the authority to change it for the benefit of both gamblers and the investors.
