Ill treatment

I 've experienced a very bad service from shopprite westonaria the one in Edward Street an I've been treated bad many times by the employees, the first bad experience was with Andrew I went there in the morning it was last year I asked him if they have their fried chicken since it was early in the morning he asked me if I see any chicken next to him,and I told not say that again to a customer the guy was screaming and shouting at me until the trolley guy came in to ask him to keep quiet the following day I went to see the manager he tried talking to him but still he was bully, the second experience I went there to buy pampers since they were on special but when I arrived by the till the price was different from the shelf I told them about the price that I saw on the shelf the lady by the name of Rebecca she was so furious telling me that it can't be the price that I saw from the shelf now she have to do transaction void because of me my husband even apologized as if it was my fault, then on the 03 June again I went there with my aunt she wanted to buy groceries for herself so I had 100rand on me I asked her to borrow me her extra savings card since I didn't have wallet with me I took Bread and milk when I suppose to pay the cashier asked the supervisor to void all of the order I made an those ladles didn't have name tags on them so today again in the morning I went to buy aquas cream for my baby I found 2 different prices again so when I went to the till to pay for my order I saw a different price again they didn't take accountability instead I was told to cancel the order I'm no longer comfortable on buying my groceries there and it's close to where I'm staying but the treatment is very bad I now prefer the other shopprite bcz I never had a problem with them but please tell them that we are now scared of going there because of their service
