I deposited total 400 euro, played over 2600 euro worth bets, but they dont want to withdraw 200 euro.

I tried with 50 euro amount with same payment method what used at deposit, but its rejected repeatly.
They never reply to my emails, on online chat it seems impossible to catch them ( today I got them, but they not replied )
