I have emailed them regarding this. I bet on a basketball game at half time.. showed odds of 1.29.. and bet365 was 1.33.. This is at half time the odds don't change.. once I submitted my bet I was shocked to see it go down to 1.18 while it was still 1.33 on Bet365.
The reason for this is because your bet stake was over the limit. This is explained in more details here :
http://www.directbet.eu/FAQ.cshtml#MaxBetAs a courtesy I changed the confirmed odds of your bet to 1.25, the odds quoted on our website when you ordered the bet, and issued an additional payout of 0.0854 BTC.
To avoid this from happening again, be sure not to send more than the maximum advised, or use the Negotiate Odds betting option and set the minimum required odds.
