Poor usability

<p>I booked tickets after hours for gold reef city theme park. I booked the 'family of 4' tickets and 1 non-rider for Grandpa. When I received the email I saw that the fine print said that the 'family of 4' package is for 2 thrill riders and 2 kids under 1.3m. Both my kids are teenagers and over 1.3m. So we could not use the tickets I bought for R655. I immediately emailed Computicket and tried to phone. I was at Cresta branch at 8 to sort it out because we need to be at Gold Reef by 8.30 to lessen queues. When I was told they only open at 8.30 we decided not to go because it will be too late . Besides, the email says that I must produce my credit card to complete the transaction. If I could have sorted it out online, or last night, no problem. I want a refund </p>
