It's a bit too easy for me to conclude that if Bet365 offered odds of 1.87 vs 1.87 on the +/- 5,5 handicap line, that the 2.10 odds must have been wrong.
Off the top of my head, that's like 10-15%. That's quite the difference because most bookies offer similar lines.
I checked your link and the only bookie with this handicap offered on there was Bet365 but I remember other bookies like Pinnacle, Betonline, Betcris etc. offering much higher than 1.87 (for example ranging from 1.95 to 2.10).
I am guessing that's because the bookies on that website didn't have those markets for live betting. Bet365 has loads of markets on all sports, it might be different for smaller companies. Betsson also accepted live bets on handicaps, but not on the +-5.5 line.
But, even if you stick to just the Bet365 odds then you can see they had 1.87 vs 1,87 meaning they considered it a pure 50/50 bet on that line. So when I got 2,10 for a 50/50 bet is that really so far off? It's just me placing a smart bet, but nothing manipulating/cheating or whatever.
I don't see it as cheating either, but the stats are showing the odds were higher compared to Bet365. I wish I had a way to check more bookies.
Let's summarize the facts here:
- the bet was NOT void right after the game finished, but settled as winner for 5 days, until it got voided. This suggests that it was in fact BC.game staff who voided it, NOT their odds provider.
It would be great if you could contact the odds provider and ask them directly. But still, if BC Game has a rule in their TOS for what they consider value betting (which is a bullshit rule to have if you ask me), I don't think it looks good for you because by signing up you agreed to those rules. We might view it as (morally) wrong, but that's the way it is. Your next option is to take this case to the license provider. Will you be doing that?
- and last but not least: the representative of BC.game on this forum told me 2 months ago "If everything you posted, including the screenshots are real then I assure you that we will make this right" after which he never posted anything in this topic anymore. So what is his assurance worth now?
Whatever the outcome and their findings, they should have responded to you long time ago. This wasn't professionally handled by their forum representative.
