I might take this to court cause I have no doubt I would win this case. Betting same amount at different accounts is proof of nothing. You would either need to prove that the same IP logged into several accounts or if using a VPN that the same device logged into several accounts with a VPN. To avoid this you would only need to pay 140 euros to me.
How much fund did you lose? A court? You even don't know the location of the company, and 140 euro is not worth to file a sue, the lawyer fee is much higher than this. Btw, have you tried make a scam accusation here:
