The worst customer service I have ever experienced...

The worst customer service I have ever experienced. I rang 4 times before saying I was not hanging up until I spoke to someone. They then said they would call me when bookings open. Needless to say they did not bother and then I happened to go online only to find it was fully booked. This is the worst organisation I have ever dealt with. If they had no spaces why waste my time promising to call. Such a joke.
