Bad service and attitude in Menlyn Fire and Ice

I booked 2 adults and one child for Protea Hotel Fire and Ice Menlyn using my Prokard membership, I was told by central bookings to mention in the comments section that one 10 year old is coming with. Today the 22nd of January 2021 at 16h20 we arrived at the Menlyn Hotel. I was told that my 10 year old needs to sleep with 2 adults on the bed with us or choose 2 single beds. I was shocked as that was not what I was told or what I intended with the booking. The suites were booked out and the failed to communicate to me. I tried getting hold of the manager and or central reservations and no one was really helpful and wanted me to pay for another room. At that time 16h40 no manager there or at central reservations. Needless to say we left and made our way home very disgusted. I have been a Prokard member for more than 5 years and has stayed all over SA, this was the 1st time that I was treated in a " bad attitude and don't care manner". Not happy ☹️ with the attitude of the front desk staff member and the Hotel for the embarrassment with my family and just plain poor judgement, no communication and failure to handle.
