Pep Store employee were unprofessional

Im so disappointed with Pep the grove mall, i went there on Saturday with my lil sister who is pregnant . i wanted to help her choose clothes as we dont no the Gender of the baby. The lady who work at Pep the grove ,her name us Agnes. she was rude and yelling at me saying im taking advantage of the pregnant lil sis. i must go and stand at the line and she is the only one who allowed to enter the shop. i said to Agnes, i am with her to assist with choosing the clothes ,and i will be the one paying for the clothes. how come i go outside and she must go inside. shes was yelling even calling the manager both of them were unprofessional. I was so disjointedness ,even end up not buying anything. as she was telling everyone at the line, you are all pregnant , came inside the shop. i went to report them to management office at the mall. they advised me to go the hello peter and complain
