Grabbing clothes from my hands

We arrived at Pick nd Pay clothing with my daughter. I heard the security lady and cashier talking and saying that there are some pants for sale. I rushed and took 3 small sizes. To my surprise the cashier came running to me and grabbed the pants on the rack and the ones in my hands to hide them under the till. I went to her and kindly requested them, she told me with such a bad attitude to come back when she's done with them. I asked her what and she did not reply. I asked her again and told me to come on the 22nd of July 2015 but one lady just brought them. I waited thinking that she give me the pants but she continued having a conversation with the security lady and other women. I noticed for the past month that you can go there and ask them for help but workers there wont even bother
