Bad , arrogant service from clicks employee manager

I went to clicks Northam plaza yesterday, and l was treated very badly by the manager (Victor). What happened is l went to store looking for Cerave Moisturising Lotion and other items (did check online if the Cerave lm looking for is needed in store, and according to online record the lotion was in store) however when I got to cerave products the lotion l was looking for was not there. I need sow a gentle (clicks staff) on the same row with some lady , l went and greeted them and asked the gentle when who can I assist with (point at the direction where the Cerave products are , since we were in the same row). The gentle man asked me more than 3 times , which product's lm refering too, and l answered him 3 times showing him the two Cerave products l was holding in my hands and he still continued to ask him which product's lm refering too. I got irritated and asked him if he will be able to assist me or not , and he shouted at me and said "Nxaa" to be (might due to l was irritated, l have never altered valgur work and any unacceptable word / language) by thay time l was walking away and when I had "Nxaa" l went back to him and asked to speak to the manager and the lady she was with (who seemed to be a customer known to him ,said to be laughing at me , that the gentle man is the manager) and the clicks staff confirmed he is the manager, and l looked at his name and sow indeed he is the Manager and his name is Victor, l then asked for the person he is reporting to and with and arrogant voice , pointing fingers at me said that he doesn't report to anything and even if l report him , he doesn't care. I have never been so hurt by a mire customer service, l am hurt than angry that's why I couldn't write the review immediately yesterday.
