That's the mistake you did why would you pay $200 to recover your funds without asking people here on the forum or those forum members who do know more about the Casino?

Honestly, it's not hard to recover funds on the Polygon(Matic) mainnet they can just import the private key to any wallet that supports Polygon Matic anytime they can send it back to you once it is imported and it won't eat too much time 5 or 10 minutes should be enough to send the Matic back to your wallet.

This has now become especially important.  Of course, everyone is watching what is happening in the usa legislative field, and obviously after the adoption of important usa laws on regulating the circulation of cryptocurrencies, which, in general, legislators should have adopted this summer.  It is clear to everyone that the main regulatory norms from American laws will be reproduced in the legislation of other countries.  Unfortunately, the time of freedom is ending, and I would even say some anarchy in the circulation of cryptocurrencies.  I say unfortunately because in practice the very invention of bitcoin and its protocol already gave a guarantee of the veracity of transactions with it, and additional regulation was needed only in cases of transferring bitcoin or other cryptocurrencies to fiat and some rules of good faith in trading these derivative financial instruments.  But that time has already gone down in history. 

Therefore, now all projects that are related to cryptocurrencies, of course, should be very careful in their work.  It is obvious that you are great, that you are closely following these aspects of your work. 
Because your Data Aggregator site is good and in my opinion is designed to work steadily for many years to come!

OP, if I may ask, why did you choose Rollbit?
I have seen several accusations of their work here, without accusing them of anything by my side, but it is evident that they are more than slow and uninterested in solving any dispute. $400 is not a significant amount for them, certainly not that they would be slow in resolving an obvious misunderstanding.
I would always choose a casino that has fast and direct communication with its users, rather than a nice interface for example.

Probably the reason is for security reason. They are using a private key that controls multiple wallet address while they currently don’t have a native polygon network available. They probably finding same wallet to import their private key for your fund’s recovery.

I agree that this can be done within few hours but remember that they have other customer and they don’t have specific support that handling this case that’s why they ask you for fee. They are hiring someone that will do your specific.

I understand now why they ask you 200$ from their balance since they don’t have supported wallet available for the mainnet of polygon.

Are you sure that you are using the correct rollbit platform? Also can you provide the screenshot of support asking you to deposit again 200$ just to recover your funds since it doesn’t make sense the need of depositing new tokens while there’s still token inside on the wrong blockchain of that same address. Matic is the token you deposited which means that’s the native token that used for transaction fee.

Providing a detailed conversation will help you to find support here regarding your case.

Edit.

Just saw screenshots from above. Why the name of the support looks like unprofessional. R0cky?

To make it easier, show proof.

Sorry about that. Rollbit account on this forum is not that active, but you can try and contact them: Rollbitcom

You can post your complaints on their official thread on this forum too: https://bitcointalk.org/index.php?topic=5326640.0

Which of their customer service that you used? I mean how did you contact them?

Some newbies do fall for this mistake. If it is not your key, it is not your coin. Assuming it is a noncustodial wallet, you will easily be able to spend your coins.

Banned? But not your betting account that was banned?

I hope duelbits can see this.

You can also send him PM:  https://bitcointalk.org/index.php?action=profile;u=2859659

Yeah!  For example, I observe this because I constantly visit your site and am quite pleased with the changes that you have been making for several years now.  I have recommended your Data Aggregator to several of my acquaintances, but they traditionally answer that they are used to Coingecko and Coinmarketcap and use information from these aggregators accordingly.  Although two of them just love gambling.  I don't even know yet how to persuade them to use a special site - your site if they often play.  But they are certainly not the kind of players who sit at the computer and play all day long:?.  And those who play in their free time and you can say from time to time. 

But, I hope that it just takes time and continue to work efficiently. 
And then everything will turn out well for your project.

This is definitely very sad news.   
Unfortunately, many projects are constantly faced with new and new requirements of regulators at the local level.  I believe that this is an ongoing process and will gradually become tougher as far as the gambling industry and the Cryptocurrency Data Aggregator are concerned.  Both of these areas of business activity are now under the special control of regulators, tax authorities and, in general, legislators too.  Unfortunately, no one, perhaps, expects from the governments of many countries, with the possible exception of El Salvador, any steps aimed at improving the conditions for doing business in these areas in the corresponding territory of this country.  Maybe you will make a request to the authorized bodies of El Salvador with a question about the possibility of opening an office in San Salvador or another place on the territory of this country.  In my opinion, the likelihood of a positive solution to this issue is high. 
But of course, if you yourself have the necessary financial resources. 
And then such problems, as you noted, may well be resolved.

You mean that any casino website needs to be registered and approved in your country for you to list it on Bitpr0 website?
But you are operating your website worldwide and visitors can come from any country in the world, there is no actual gambling happening in your website.
I really dont understand so much complications with regulations in all the different countries.
