I am very unhappy with the service

Last year I received a letter with 2 free nights b/b, so called a joburg number to book got confirmation number and hubby and I took off from work due to it being our anniversary, what better place to be than in wild coast!. So hubby and I left early than normal cause my hubby made other plans before our reach to wild coast. At around 10 that day a lady nokwanda from wild coast called and informed me that there is no room available and I cannot go there, so upset and sad I just left it, then recently ive been getting sms for free nights and even got a birthday free night but so sad that whenever I call there is no availability??? Before having a gold card and calling in to stay using points for a weekend (40) use to be worth it for us normal people who want to take a break and destress in the casino, now going to wildcoast would mean paying nearly R2000 for accommodation for a weekend and spending close to R4000 in the machines and you have to pray that the machine even pays you anything . Please dont send me free nights for weekdays cause its not possible as I work! I hope some changes can be made as having a gold card seems to have no value if we cannot book any more.
