Refusing to pay me my money

Dear,
I contact you from next reason. Trada casino decline to pay of amount1394.8euro. I earned that amount gambling the three different slots (" Dead or Alive", "Starburst" and "Jimmy Hendrix", between period 04.jun - 07.jun. Trada casino refunded me my deposit in the amount 100euro.
I contacted them( live chat) several time for different reasons as bonuses, wagering and need documentations, how i informed myself that everything has been all right. After, uploaded my document i received next e-mail:


Hi Andriana,

You requested a withdrawal at TradaCasino on the 7th June 2016.

The banking department have reviewed your account and unfortunately we have been forced to void your bonus winnings.

Fraudulent activity, which has breached our terms and conditions, has been detected. For this reason we have processed a refund of your deposit of €100 to Neteller and closed your player account at TradaCasino.

Regards,

James.
After that e-mail, i tried to make understand the situation and i contact them via e-mail and i said:

Dear,
I contact you for next reasons. You denied to pay me earn money from your casino, and not explain me what are really reason. You mention unauthorized actions. I can prove every documents and identity and also I can do over the skype or other alive way which you need. I hope that give me information how we overcome this problem.
Thank You
Andriana Stamenkovic
The response was:

Hi Andriana,
I am sorry, but I cannot give any further information, other than to let you know that fraudulent activity has been detected.

As we have now closed the account and refunded the deposit I am afraid we cannot continue to engage directly in this matter.

Regards,

James.
It was completely unacceptable for me and i asked them next:


I am completely sure that you have to give me a evidence which that prove. Also I am sure that some institution as your banking institution have to prove facts. Your terms and conditions probably contain next instance which I can refer?
After, they directed me, on THE POGG and they sent me this directions via next e- mail:
Hi Andriana,

We have refused your payout based on:

Legal Use: Section i

TradaCasino reserves the right to suspend your account pending investigation in the event of the casino having reasonable grounds for suspecting that you have been involved in any form of collusion or fraud during your use of the casino platform, website and/or systems. We also reserve the right to withhold the whole or part of your account balance, close your account permanently, as well as recover from your account the amount of any winnings, pay-outs or bonuses which have been affected by any of the following activities.

You can escalate the issue with third party such as ThePOGG or at Online Dispute Resolution.

At that stage we can share the evidence we have gathered with the third party, which proves that the terms under Section I have been broken.

Thank you,

James.

I will upload the same documents which i uploaded The Trada casino and You will see in attachement.
