bad attitude and unprofessional

Iwas at pick n pay yesterday, I bought 2aqua fresh kiddies tooth brushes and below that stood a price of R7,90. I get to the till and I say that's not right they send someone to fetch the label that was below the toothbrushes and it said R7,90 Olivia then approaches the till and says no its the tooth paste price and she insists it is yet I just bought aqua fresh toothpaste and it was R6,90 and Olivia argues with me after I told her is price you see is price you pay and she tells me no we must check the security cameras and I walk withher to the room where Gavin is sitting and I am speaking to Olivia and she says Angrily \Can you just wait gou!"I was appalled by her response and asked what slang are you speaking its unprofessional and then gavin jumps on saying I must read pick n pay policy and he must check the cameras and I say price you see is price you pay and he tells me no. I walk away and go to the till pay anand I told them I will hello Peter then and gavin says report us to the highest management and then he tells the security at the door you don't ever let this woman in our shop. I want the area & store owner to contact me so they can bedisciplined for their attitude"""
