False advertising on Daddy's deals

I booked and paid for an Easter weekend through Daddys deal. Received a confirmation email stating that my booking has been paid for and secure. I then receive a email stating that there has been a mistake and i need to move my booking or cancel it. Which is very unprofessional. After paying and securing the booking. Which is false advertising. And customers hate to be misled. Something needs to be done to this company as they have no right to cancel my booking especial after we have paid and i have supporting emails stating that availability for the Easter weekend.
