Shoe Show Moultrie complaint: Customer service

I visited a show shoe today in moultrie,Ga with my two young daughters. There were 3 women working. Two white ladies and a black woman was working. I had brought three pairs of shoes to the counter and was rung up by the older white lady with glasses. I seen a sign where you could buy a pair of shoes and get half on the second pair. I was informed that I had to get a certain brand in order to get the discount so I went back and got another pair. The black lady had to return my items in order to give the the shoe half off. I assume it was the manager because she had keys that was doing my transaction at this point informed me that I needed a id to do the return which I found very prejudice because I didnt have one. She refused to do my return. I had to go to my car and get my sisters. The woman had a rude and nasty attitude. At one point she didnt want to accept my phone number to do the return. She than proceeded to answer the phone and carry on a full conversation with that person. She was so rude and inconsiderate of my time and money I was spending. She than proceeded with the return after I asked the other associate to ring me up because the cashier was busy on the phone. She than refused to put my items in a bag and asked the cashier that rung me up the first time to bag my things and walked away. I asked the black cashier for her name and she refused to give it to me. I will be returning all 4 shoes tomorrow and speak to the store manager about her behavior. I would not recommend this store to any of my family and friends. Worst customer service ever.
