BetBoro Casino - Took my money without any explanation and proof

I opened account in Betboro, I deposited 200 euro and took 50% welcome bonus. I had good luck and managed to reach 1 247,xx euro balance while wagering bonus. After I completed bonus wagering I verified my account as Betboro asked. Documents accepted but Betboro asked additional selfie of me holding ID in my hand. I sent selfie and then got e-mail:

“We have detected that you have tried to manipulate our system and you have violated through your actions our terms and conditions:
3. Should there be a suspicion, presumption or an indication of fraud, betboro has the right to cancel all bets with the same person or persons without notice and freeze the entire account balance.
3.1 Criminal acts and acts manipulating the system will not be tolerated and will result in the immediate closing of the customer’s account as well as completed and uncompleted bets being declared invalid.
4. Betboro reserves the right to close account in any case of attempt of fraud against the company. This includes any system based on the use of software, techniques, computer, machines or similar tool.”

I asked in Betboro live chat about what I have done. Customer servant denied to give me any explanation and closed live chat. Betboro also blocked live chat from my IP address so I couldn’t reach them again.

When l logged in I noticed that also my whole betting history was deleted. I couldn’t even find those canceled bets as everything in account history was deleted.

Betboro is stating there that I have manipulated system and attempt to fraud. I have just placed normal bets mostly in live and haven’t done anything wrong. In my opinion betting company is going to make fraud against me. So far I haven’t got any proof and don’t even know what I have done here. They just took my balance.
