Casino refuses cashout and offers bank transfer for which I don't have reached the amount

I want to warn other players against using this casino, as they will do what they can not to pay out winnings. I took the first deposit bonus with a deposit of 30€, played the bonus through and ended up wirh 284€ that I wanted to cash out. Problem: even when I paid by Credit card, only option was bank transfer with a minimum of 500€, which I find very unfair. All casinos I played in offer more than one option for cash out, and from their General terms this is not mentioned. I contacted support first time , and was instructed to make a Skrill deposit play it through 3 times (which I also find unfair) but I did and requested cash out by Skrill.

I tried this before in other casinos and they were always helpful in providing other withdrawal options. Cash out was rejected despite the instructions, with the message that I should use Bank Transfer option. Contacted support 2nd time, they told me that the first agent gave me bad advise, that I should use bank transfer but minimum is 200€. Tried this, but of course minimum remained 500€. 3rd agent said the 2 first gave wrong advise, and that for me unfortunately Bank Transfer is the only option despite of my Skrill deposit and fully verified account. I was left thinking, which of the 3 agents gave the correct version ? Therefore I submitted a claim to the casino, which remains unanswered until now. I played many casinos and never had any complaints but here I feel treated unfairly- a min cashout of 500€ should not be the only option.
