Dollar General review: The behavior of a manager

The incident happened on March 21, 2020. The store was in Pinnacle North Carolina. The store number is 16792. The person I am coplaining about is the manager of the store, his name is Bob. I went in the Dollar General on Saturday March 21, 2020. I told the clerck I had brought some clothes back on March 19 to exchange with my reciept. I had left a schick intuition razor in the bag that I had bought on the 18th. The manager heard us talking, he was coming from back area of the store. He ask what do you want, with a hateful tone. I told him about the razor and I aslo told him I need to exchange some clothes. He said with a very hateful tone; you was just in here on March 19 to exchange clothes. I told him I had bought clothes on March 18 and 19th. I told him I just got different sizes and thats all I want. He said, go ahead. I was back there looking for the size I needed and heard him talking about me to all the customers. He said, she brings stuff back all the time. I then walked up and said, I do bring things back a lot but I spend thousands of dollars in that store. I just live 2 minutes from the store. I was so embarrassed. He had no reason to talk to me that way. I was only wanting to get the right size of clothes. I told him I didn;t deserve the way he treated me. He said, very hateful, I am sorry, have a good day. He didn;t even put my stuff in the bag. I hear him talk to others like their thieves. It's unreal how he treats people. I really don't think he should get by with treating people bad. I will leave it up to you how to resolve the matter. Please do something.
