Includes screenshots of some of the bets I placed, parts of my transaction history, the KYC approval and confiscation email from Winna.
I would suggest you to remove or hide your name from the mail and avoid doxxing.
that's just his winna username.
I could not find any unusual betting patterns from the images you posted, it has straight forward bets provided by the sportsbook, team has to clarify further about their standard betting behavior .
same, i took a look, and i don't see anything that could be considered "suspicious betting activity", all the bets were on top tier leagues, UCL, PL, LaLiga and 1 NBA bet.
the stake amounts also look normal, no weird amounts which are usually a giveaway for arbitrage, and they can't say it's "late betting" just because he placed most of his bets a few minutes before kick off, everyone does that.


but this does look like value betting to me, but even if OP was doing that, so what? he didn't break any of their sports terms:
https://winna.com/sports-terms (didn't find anything about valube betting not being allowed)
they should pay his wins, then limit him/ban him if they don't want him playing on their site, voiding his wins is a scam.
