Very unhelpful rude staff

I was at Capegate and they overcharged me a total of R18 on goods purchased. I went to Capegate, an out of my way inconvenience, since Haasendal is always without stock. When I went to Haasendal, the next day, to return some goods bought at Capegate, I was told they can't do this or refund me the overcharged amount because it is not the same shop. So I asked how are all Dischem shops not the same? The "returns" lady (who refused to give her name) then said she will check the shelf and phone Capegate. After a while she returned from checking the price and told me she will now phone Capegate. After waiting some more, another woman from cosmetics came and said she will phone Capegate and I asked why hasn't anyone phoned already, I was in a hurry for an appointment. I then asked for the manager, who they said was standing behind me, Stanton Booi. At this point we were surrounded by about 6 *********** staff from Dischem. So I took his name and asked him what he is going to do about it. He was just staring at me blankly, so I said I was going to report it on Hellopeter because now I have to drive out to Capegate and use additional petrol to be refunded for products that Dischem overcharged me for and I was about to leave. He said they told him everything already and I was welcome to report them on Hellopeter and he won't be refunding any of my "prescriptions" - whatever that means, because everything was cosmetics. So I asked if he is refusing to refund me for my goods and overpriced items and he said the cosmetics woman will phone Capegate. At this stage, all 6 or so staff were just standing there supporting the woman who hadn't yet picked up the phone next to her, but was maybe waiting for some sign? So I asked when is she going to make the call? It was a really weird experience. Everyone just standing there, nobody phoning Capegate. Eventually they relented and she managed to make the call. In my whole life I have never come across such stubborn unwillingness to help a customer that YOUR store overcharged on items. This incompetence carried on in the phone conversation - trying to establish if the stores actually charged the same prices for all items! and indeed they do! What a miracle that both your stores actually sell the same product at the same price that is different on the shelf! The same error happening in both stores, should I be surprised? The staff seemed very surprised. Needless to say, I found this incompetence highly irritating on top of wasting my time. And besides all this unpleasantness and stubborn unhelpfulness - the other day I bought >R3000 at Haasendal but went over my transaction limit for the day, having already drawn cash earlier at the ATM. So I could only buy R2700 worth of goods and had to return the next day to buy the rest. But you know what? Haasendal treated me like a ******** that day - they got TWO cashiers to come and count the R2700 cash and scan it under UV!! Just because the security setting on my bank account limits daily funds! The person accompanying me said they thought Dischem treated me like a ******** and said they were disgusted and I made an excuse that you probably had to check cash. BUT then guess what?! When I returned the next day to buy the rest of the goods, I bought more things, totalling >R1000 and paid cash, and NONE of the money was scanned by UV and they didn't need TWO cashiers to count the money! So, you know what? If I am unwelcome and being mistreated like this by your Haasendal staff, I want you to tell me so, so that I can avoid buying from your store. I want Stanton to contact me and apologise for himself and his staff and let me know how welcome I am.
