Central mall yelahanka - Harassment at shopping mall

It's about the harassment that was happened with me at central mall, yelahanka. I bought a jeans from the store and made the payment at the billing counter. Cashier forgot to remove the tag from the jeans, which beeped while exiting from the store. The unprofessional, untrained staff told me to remove my clothes in the changing room and a lady staff with come and check. Despite of cross checking the bill with the item, they asked me to do so. Manager told me that it's a protocol since items are missing from the store. It's hard to believe that such unprofessional people are hired ,who gives such bullshit reason for the harassment. None of them were sorry for what they had done. Instead of just checking the tag, they questioned me in an ugly manner. They just disrespected a women's dignity.
