Bad customers service with bad manners and harassment

On the 03/01/2019, we visited the table Mountain cableway. I had a child who was celebrating his birthday and had to be refunded. One of the attendants properly assisted me to get a refund and gave me other tickets on top of the tickets i received at pick and pay. When we returned from the round abouts of table Mountain at 16:00, at the check out point we gave the attendant the tickets we were given but failed to scan, i then decided to give her the pick and pay tickets. Then at that moment another attendant lady in uniform came with a negative attitude towards us and just grabbbed the tickets from the other attendant. The lady then started to interrogate and harass us on an ill/bad manner and negative atttitude. She spoke badly with us as if were *****s infront of other customers. Even if told to make enquiries why we were given other tickets she just continued to display her bad manners towards us which was a very unsatisfactory service. I felt very much degraded as a customer and also harassed
