False advertising.

I made a booking with booking.com in April I saw no problem making the booking 6 months ahead as it had said it's free cancellation 7 days before the booking. My booking was massed up I requested one room for 2 adults and one 3 year old, but confirmation was only 2 adults when I asked the lady she said it's only two adults. I called the hotel for the confirmation and some rude man who answered said he knows nothing my booking is with booking.com I should call them. After the bad service and rude receptionist. I no longer wished to go there so I asked for my refund so I can book elsewhere. To my surprise I can cancel but there will be no refund what happened to full refund if it's 7 days before your booked date. Don't even bother calling them you will just be transferred to one person to another no one willing to assist if the agent you made the booking with is not there like this information is not stored in a computer, in one instance I was on hold for an hour.
