poor customer care

Purchased 2 x combo tickets online on 3 December 2015 to take our soon to be 2 yr old on her 1st trip to ushaka who was ecstatic as she loves fish and playing in water. Called their office's on 5 Dec 15 to enquire as to whether the proof of purchase is sufficient as I did not receive any tickets via e-mail. I 1st spoke to Ayanda who put me through to Amanda. The called dropped half way through, I then called back and was put through to Kuben who said he will get Amanda to call me in 5 min. 5 min came and went and I called in again this time going through to Amith who put me through to Kuben who advised me to come to ushaka and speak to Kieran or Arnold and ALL will be resolved. I drive 30km with my wife and child only to get there, wait half an hour without seeing Kieran or Arnold, only to be told that the systems are offline and they will call me when it has been sorted. I am yet to hear from them. This is very frustrating as I have paid for something I do not have and had to explain to my daughter why we were unable to go in. I hope for a speedy resolution.
