Bad customer service - Consumer Complaint for PEP STORES

I went to pep in kwaguqa mall.i am hurt about the way they treated me.i wanted to make a paxi they told me to wait for about 30minutes after that they told me they can't help me if I don't have the store code.According to what I know they were suppose to help me find the store code but instead they told me to comeback when I have a store code.had to take a taxi back home.i am so disappointed in their service
