They have another odds provider for esports in addition to pinnacle, which is where these odds came from. I don't know when the bets were cancelled, regardless it's not acceptable for them to cancel only the bets I placed which showed to have +EV after pinnacle opened, and keep the rest. If I had bet on the other (-EV) side of the "bad odds", would they cancel the bet? Unlikely. I did email support, we'll see if they have any excuse.
