Portao Diaz Hotel - booking query difficulties

Inquiries for a booking was made on the 13th November. I was told by Kim that there were rooms available for requested dates (24th Dec - 28th Dec) and when wanting to book, all of a sudden they were fully booked and could not accommodate us for the rooms that we wanted. The dates for availability changed to only from the 9th Jan. We have expressed our disappointment and an apology was offered as she had not mentioned exactly which dates were available for which rooms. <br> <br> <br> On the 14th November we received a mail form Jaylin to say they have rooms available form the 2-8th January, and she asked if she should book it for us to which we agreed. She had then sent confirmation/reservation numbers, but the prices differed. The original amounts were R795 for the family room and R695 for a double room which is not what she had invoiced us. It was more, R900 odd for the family room which now included a kitchen but this was not asked for. <br> <br> We are wondering, why is it such a mission to get a room booked at this Hotel? Why are bookings made and then customers are disappointed because it is not the correct room or its a case of no availability??
