Unibet and payment missing

I have web site about on-line gambling and I promote Unibet. I work 1,5 months and I earned lot of money with Unibet. But I read some posts on few forums about Unibet. People say that Unibet doesn’t send money or money transfer is waiting and waiting. I am shocked. It means that my money is gone. Is that true? Does Unibet pay money at time? When they pay (which day in the month, every 5th, 15th, 20th…)?
