Family Dollar

I purchased a fan from family dollar located at 4646 s halsted and it's missing pieces I went back for an exchange they didn't have anymore and the employees including the manager was laughing making jokes saying why you put that broke fan back on the shelf anyway I asked to do a even exchange not money back and irenea began calling me sexual names I immediately asked her to stop and she kept on calling me mamas, baby love and other names I felt disgusted standing in there at this point I would like my money back I shouldn't be treated like that i'm a customer spending money why are you selling broken items to people I work hard for my money
