Regarding the absence of this information in the Russian version of our Terms and Conditions, we kindly direct your attention to the following page:
https://vave.com/ru/help/sportsbook-rules Section 2.18 states: "In the event of a discrepancy between the English language version of these rules and any other language version, the English language version shall prevail."
This doesn't look like a simple discrepancy. You decided to restrict Russia in your terms and you didn't specify or completely omitted that in the Russian translation? You can't be that dumbed to overlook this matter.
I agree with other's statement that it was only added just to avoid paying players like the OP.
