Edgars has violated my human rights & degraded me

Walking out of Edgars straight after paying at the till I was stopped by Sonto a security, she went through my Edgars pkt without even a hello and asking if she could, as I'm asking her why she is going through my pkt with out asking me she proceeds to open my Baby bag in the same trolley without asking me again. She has a bad attitude and says she has the right to look through my personal belongings without asking me, and she didn't even ask me for my till slip. Went to speak to the store manager Charmaine to complain and she believes that Edgars has the right to look through personal belongings of their customers with no prior concern or evidence of wrong doing. She apologised for the way sonto spoke to me but she still believes that Edgars can look through personal bags with no prior evidence because people find ways of *****ing, those where her words to me. I was embarrassed at the exit to Edgars by security & in the customer service department with Charmaine, I felt that my human rights where violated and degraded going through my personal bags without permission and that my character was up for debate the way the manager spoke to me like every customer is a possible *****.
