Misleading pricing, rude tellers and no refund

I saw what I believed to be a 3 for 1 special at Clicks on cotton-wool make-up wipes (I have photographs of the notice on the shelf which I believe is very misleading) I made my purchase and aid with my Capitec bank card and then queried the slip as I had paid for 3 x the item. A huffy store assistant told me I was wrong and then called a supervisor who was EXTREMELY rude and condescending (I am 51 and she is 23 at best) then when I called her out for being rude and argumentative she rudely retorted that she was not being rude ! I then asked for her name and she started to walk away so I got a photo of the back of her head. I asked the teller for a refund and she said the money will be put back on my card (I know it doesn't work that way with Capitec) and said so - she said again that I am wrong. I asked if it will be immediate and she said yes. I got my phone out - indicated the purchase transaction and waited for the reversal. Nada. She then changed her tune and said it may take a few hours. The Manager was not in store so I then spoke to a dismissive woman by the name of Debbi who further exacerbated the situation. I even struggled to get copies of the reversal transaction - the teller wanted to keep the only copy - rather irregular. I do not appreciate rudeness nor my time being wasted and I certainly will not appreciate Clicks retaining my money (in excess of R130 !) This occurred at Long Beach Mall Sunday morning around 11am
