OP claims their account has been banned, so there is nothing to take a video of. All they could do is take a video of unsuccessfully trying to log in to their account.
Rollbit Razer has already posted in the thread, saying they are aware of the player's activities and that they have had accounts on Rollbit before that have been banned. Since the previous account(s) got banned for sports abuse, it safe to assume the most recent one was also banned.

The only question that remains is whether hugarden2 is the person Rollbit suspects them to be. 

Since this case involves an issue with sports betting, I don't think Casino Guru and Ask Gamblers will consider it. I remember they only handle casino disputes looking at some past cases. You will have to find someone else. Some services that were mentioned before include The Pogg, Casinomeister, and Gamblescope.

I don't know anything about the quality of neutrality of their services, though. That's something you will have to check yourself.

At first, Signature Company doesn't require participants to post on the Scam accusation board. So, whoever writes here, writes with genuine interest. I hope you got it.

As You can see, They are confident with their decision. They accused you of creating multiple accounts and said your old account was banned from their casino while you claimed you did not play there before. Is there any possibility that someone from your house/office uses Rollbit using the same internet? Or, Did you use VPN to register or play on Rollbit? Those could be the possibility if you did not lie. Still, If you are also confident, You can file a complaint at ask-gamblers or whatever mediation service they support.

@Rollbit Razer, Would you mind cooperating with 3rd Party mediation service, as OP claims he did not play on Rollbit before? If so, Which Mediation service do you guys support? Of course, we don't want to see a bad reputation on your platform.

The problem is it's not your "bitcointalk" account.

It's because you are getting prohibited due to abuse and then opening another account again. If the player are getting banned due the abused or something like broke their team & condition, that's mean they are no longer to be accepted for the service.

If they broke another rules by opening new account while he already being banned, casino are gonna to block you again.

looks like they are confident in their decision and the only thing you can do now is either continue complaining here or complain to their license provider regarding this issue.

@Rollbit Razer, quite glad that you could reply here, It would have been nice to see how you can detect abusers but I'm sure it would pose a risk to your process of how you catch them.

Firstly, thanks for the message about this thread holydarkness!

OP here is a prolific sportsbook abuser, previously banned from our platform for circumventing sportsbook limits (creation of new accounts).

Unsurprisingly, and similar to their other attempts to abuse our service, they've also created a new account to complain here.

We've invested significant resources into technology that allows us to catch abusers like this, we're confident with our decision here.

You weren't banned for what you said, but for what they believe you did. The discord screenshots mention sportsbook abuse and using multiple accounts. If you had previous accounts on Rollbit (which you won't admit if you have), they would have noticed them while doing their manual checks. That and some sports betting abuse are the reasons for your ban, not the fact you made one bet or talked badly with their staff.

Get in touch with their forum admin if you believe you are innocent.

If you aren't, don't waste time by prolonging the inevitable.

I read the Full Conversation between you and the Support Agent. Weirdly, Rollbit Takes that long to check withdrawals.
I would ban/block you as well if you talk like this. You don't have to freak out and react like this when you face issues in online casinos. I believe if you were not rude to the support agent, you would likely get a response from them, and you could continue talking with them. They blocked you just because of your rude behavior.

I suggest you contact them again via Live Support or Email and write your words politely. Suppose you don't get any response from them. Contact their Forum Representative account as they are active in this forum. They continue to maintain their reputation over the years. They are unlikely to ruin their reputation for 255 Dollars.
