Hello there. I must say that showing screenshots is a perfectly smart solution. Now that I'm thinking of it I have seen that before here on the forum, and I'm quite sure it was the same issue you're facing now.
I'll conduct a little research to help you out. Meanwhile, do you use any plugins in your browser? I have a feeling that some kind of active translator plugin might cause such silly behavior while writing a post here.
Regarding your issue, I'm glad to hear we talk solely about winnings from the no deposit bonus, because at least you may consider whether it is a worthwhile deposit in the casino.
Yes, most likely, you need to deposit in order to verify your payment option so it can be later used for the withdrawal.
However, I would be hesitant. It sounds risky to deposit at a casino that seems to ignore you for longer than a week. Wouldn't you say?
