MIMIQ promenade mall Mitchell's plain

Good evening I had a bad experience in MIMI.Q store in promenade today where a cashier forgot to check out a electrical nail filing product my daughter board so I ask her to see if it works Then a guy came he's name is Edward he said he is the manager of the store So he checked it out in front of me and I saw he was struggling with it and I tried and I told him that the product is not working properly so I told him I don't want it he must refund me so he got angry and told me no he not going to refund me and I don't know how to use it and I'm stupid Moral of the story is he is very rude and need some manners and he is not management material please give him other duties as he doesn't know how to treat customers I will never let my daughter buy at that store again and I won't recommend someone there
