I have a comparable problem....I bet on Under 4,5 corners first half in the match Metz-Nantes. The count was 0-1 and there were 10 minutes played in the game. So this line was perfectly normal.....it stays open bet for a long time....and then at around minute 35th of the game (corner count still 0-1 so my bet was almost for sure won already) and the bet suddenly changed from open to cancelled. Without any notice!
What is this? If your odds provider did this, then you have to understand this is NOT fair to your customers! The odds were definitely not wrong because other bookmakers had a comparable line. And IF you cancel a bet you should do it RIGHT AWAY and not wait 25 minutes until the bet is 99% sure a winner and then cancel.
I expect you to have a look at this and fix this! My bet ID is 01451468
You have to understand if you start to cancel a lot of bets, customers will run away! Especially cancelling late without any notice!
Sorry for being kinda late, we're looking at the canceled bet of yours, I will provide you with detailed information throughout the day.
P.S - our betting ODDs provider had an technical issue, that caused the cancellation. (we're monitoring and evaluating the problems at this moment).
Thanks. I was emailed 2 hours ago that the winnings I would have received from the cancelled bets (should they not have been cancelled) are being credited to my account in the form of a 126mbtc freebet. I find this a good solution. Just wanted to report this here. Now let's hope your odds provider gets things sorted out so these cancellations will not happen often anymore, and if they do, they should at least cancel straight away and not when the bet has already won for 99% sure. But I'm happy with the current solution.
