Dafa and IBC do void rather short periods before match starts - was no obvious mistake in their odds, but twice cancelled, which cost me around 900€

Played first goal - first bet on 1.9. @1,95 (dafa)
another bet on 3.9. @1,84 (same match at IBC)
other bookies were around 1,75-1,80 at that time
both bets voided around 2h prior match started late SAT (I was not home so didn't realize that cancellation)
As that has happened the second time now already I must say
NEVER EVER AGAIN betting on first goal at ibc/dafabet
