Bad customer service by Pick n Pay Qauli Save manager

The Picknpay qualisave in jabulani Mall they recently just opened...So I went there to run errands and with black Friday coming I saw 2.5 Selati White sugar with R33.00 so I took 2, to my surprise when I get to the till the sugar it's R69 for 1 so after a little bit of back and forward with the cashier she called her manager for me. Mind you she didn't even have a name tag on her uniform so i explained my problem to her and all she could say was that I'm ******** and I asked her how is she telling me I'm ******** she then further told me that I need to be realist about prices in this day and age theres no way a 2.5 sugar can be R33.00 then walked away while I was still talking to her. Then i asked her colleagues what's her name and they told me it's Khabonina. Well I know it's impossible for sugar to cost that less but i mean it's black Friday and that's no way to talk to a pick n pay loyal customer worse cause they just opened so is this the way they wanna run their business. I doubt I'll even go back because of Khabonina the manager she has zero people's skills so I suggest Pick n Pay sit her down and talk to her cause I doubt I'll be the only customer to complain about her if she carries on like that.
