Refused entry

Booked through RCI a 2 bedroom unit. When booking confirmation came through it specified a 2 bedroom unit sleeps 4. On the same day the resort were contacted and I requested a unit which sleeps 6 as we were 4 adults and 2 small children. the resort referred me to RCI which was telephoned and they said they will get a bigger unit. On arrival at the resort I was refused entry as the unit was for only 4 people. The resort confirmed that I telephoned them. Rci was contacted and they also confirmed that I phoned them. After about 2 hours waiting RCI got accommodation for us in Margate which was emailed to Caribbean Estates. I then requested for visitors during the day but Mr Prinsloo said I will only be allowed visitors for 3 hours that evening but said he will phone me in the morning to confirm whether we can have visitors. He phoned me the following day and said management refused any visitors to the resort. (They knew we had a 6 sleeper unit in Margate). I went to the resort 2 days later but my gate pass was put on hold. We were only 2 adults and 2 children in the car. Had to wait for them to activate the gate pass. We only spend 5 minutes in the resort (was booked in for a week).
