Hostile and awful treatment

was @picknpaystonehill (Stonehill crossing) this morning and I was confronted by a very unpleasant experience. I saw a Russell Hobbs stainless steel breakfast pack going for R1249.00 as I went to pay for it at the till it went up to R2000 something , then I told them I was going to pay for the price on display but the manager ( Jason) rude as ever refused to give it to me , he went as far as to tear the original price but fortunately i had taken a picture already started cussing at me , and call the securities on me I felt like a ******** and I would like @picknpayheadoffice to please look into this matter coz the law clearly states that I be given at the price that is on display.
