Problems with BetChan casino: refusing to pay out

Hello admins, here’s the thing: I registered at bet chan and they gave 33 spins. I spun them and won about 450 rubles, wagering x50. I withdrew, wrote to support, they tell me about the spins withdrawal 2,500 + make a deposit and submit documents, i.e. a selfie with passport and on a piece of paper that it says hi betchan. I tried to take a photo at home with my Sony camera but it didn’t work, went to the city, took a good quality selfie, submitted it, they tell me the passport isn’t visible although everything is clearly visible and very well since it was done with a professional Nikon camera. I then submitted the passport itself up close, they told me in chat to wait 10-15 minutes. Evening came, silence. I write them in chat asking what’s up with the documents, they say everything is OK, the documents are approved, according to withdrawal rules 2,500 I had to make a deposit of at least 500. I made it, and as soon as I did they write in chat that you have duplicates. How does this happen – first they approve the documents, say everything is OK, you can play, and then they deduct the whole amount and ask to top up another 50 rubles to withdraw the money that I deposited 500 because the withdrawal min is 1,000 rubles. I don’t understand why give registration spins without deposit or spins you win from and then not want to pay – then it’s the passport is not right, then they say duplicates, they tell me that I have duplicates although I’m in many casinos and don’t suffer this and I perfectly understand how this might end. My opinion is they just don’t want to pay the 2,500 that was won from the 33 registration spins. Help, maybe you can do something for me? I want to stay with this casino, I don’t want to be, in their opinion, a bonus hater, I really liked it there
