Mtachbook warning: check your settled bets permanently

[SBE]

It happend second time in past 14 days.
They inserted a wrong result.
This night it was Opelka vs Donaldson tennis.
Instead of winnig Opelka bet I have found (according Matchbook) that Opelka lost.

So, please, be very carefull when using Matchbook.

If you are having similar experience with them this year - please share it.

Thank you.
