Binarybet.com error

Has anyone else fallen victim to an error by Binarybet.com. On the midday 10 point range FTSE market they initially paid out on -30 to 140. I withdrew the proceeds of my bet on this outcome but later they made a 'correction' leaving my account in the red.

Well ive had IG take from my account in the past by mistake, the settled the bet the wrong way, 0 instead
of a 100.

They were very quick to repay me.
