WHY BETFAIR OFTEN DELAY THE SETTLING?

Hy guys. I have often the problem that games who i win, and only big wins, i must every time, contact support for settling. Again and agian and again... wtf? No other bookie have so problems. Now on this day is the game on ISLAND FOOTBAL: Thor Akureyri
0-0 (p.0-0) Aegir Thorlakshofn - i bettet over 30 Euro on 0:0 - (Sportsbook) - Win over 1000.- all others under 2,5 under 3,5 are settled.. but this one AGIAN no.  I bet on a lot other Bookies, since since years i dont had any time a problem with this, only here. Do you have similar experience?
