NextCasino - Misleading currency issue with Ezugi Live Roulette

Hello, I doubt if this casino deservs such a hihg rating. I am a new player. After registration I used 1st deposit bonus then I cancelled it and made deposit PLN400 (this is the currency I chose while registration). I played Live Roulette (Evolution, Immersive, Auto) and won total 800PLN. Those live roulette table are very fair and transparent: you see the balance in your currency and have detailed history of playing (see: attached file no. 1). Then I opened Live "Roulette B" (maybe "A" - I'm not sure - NextCasino didn't give me any details about this bet only general info - Attached fiile No.2). This Live Roulette "B" seems to be quite different from Evolution or NetEnt or Playtech - looks like an Asian one. I placed a bet 100PLN on a column and didn't win but noticed that I had been charged not PLN100 but PLN517.32 (GBP100). Attached file no. 3 shows that in this live casino room there is no information what currency you play. Moreover I could not find any history record of my bet in this casino room. This is a very tricky and unacceptable way of cheating players who are not aware that whatever currency they registered in this casino (PLN, RUB, NOK, EUR, USD etc.) they will finally be charged in GBP and may loose a lot of money.
My intention was to place 100PLN and without my permition they charged me 100GBP. I lost PLN417,32 and hope that you will help me get the money back (difference between PLN100 and GBP100).
So far NexCasino hasn't reply my complaint. They just told me to check the bets history record and keep in mind the time difference GMT and CEST.
Regards,
Mariusz
