Why my account balance on adfocus became negative?

[yashchauhanz]

My account balance suddenly went into negative suddenly. Please tell me why did it happen because i did not withdraw my balance because i was having less than 10 dollars still suddenly it went from 5 dollars to -8 dollars. Otherwise I have no issues so far. Adfocus is the best platform to monetize your links. I am regularly getting payments on time. Love you Adfocus!
