Proof that bets can come in, be received while your minimum odds are still available, yet not get confirmed!!!!
You are right, your bet did not confirm due to a rounding issue on our website.
Following is an explanation as to why that happened.
This is the first time we became aware of this issue. The other bet that you complained about was not affected by it.
Our automated betting system is working with decimal odds. Our website on the other hand has an option to display odds in American format.
You ordered this bet when the odds were 1.78 decimal while viewing odds in American format.
You selected the "Negotiate Odds" betting option and by default, the minimum odds is set to the current odds.
1.78 in American is equal to -128.2051282051282. When populating the default minimum odds field, all numbers after the decimal point were discarded and so the minimum required odds were set to -128.
When your bet was received, our automated betting system converted your -128 minimum American odds back to decimal, which turned out to be 1.78125 and since this number was higher than the current odds of 1.78, your bet did not confirm.
