Market:  https://fairlay.com/archive/pain-vs-istanbul-wildcats/?referral=b8378473-cd8d-44e9-bd6d-130770e61974, you can see the time of the bet in UTC is 17:19:14, May 10th.  I bet on Pain Gaming, and then they won.  You can see here: https://imgur.com/a/p8Dss6j, the bet is voided.

They claim (in chat support): Ognjen-Support: Hi, Braille. Those orders were placed after the match started and according to our rules, "Bets placed on non-live markets after they started ("late matches") are subject to be voided. Knowingly betting on non-live markets after the corresponding event already started is regarded as fraudulent activity.

Ognjen-Support: We've double checked it and your orders were placed six minutes after the map started.

● Braille: My single order was placed as both teams had 3 players drafted

Ognjen-Support: If you have proof that your order was placed before the match started please let us know and we'll look deeper into it.

I gave them proof, they looked deeper into it, and they continue to deny me my winnings.

The evidence:  https://cq-esports.com/matches/lol/284134-pain-gaming-pain-vs-istanbul-wild-cats-iwc-msi-10-05-21.  Start time of 17:14 UTC, end time of 17:51 UTC, May 10th.

The listed start time appears at first to in fact be before the time of my bet.  However, if you look at the duration (28:49) of the match, here: https://gol.gg/game/stats/31273/page-game/, you can infer that the match ended at 17:51, started at roughly 17:22 (51-29min duration=22), and that the 17:14UTC start time is when the draft started, not when the match started.  This proves my bet @17:19:14 was before the match started, and must be legally honored.
