I went to Ackerman’s Sandton Store to do a refund on an item I had my slip but didn’t have the bank card with me I had to wait for 15 months for a supervisor to come and do an override when he came the gentleman by the name of Thato he never apologized for making us wait after that he didn’t listen to me nd just gave me attitude dat he won’t refund me he then took my slip nd said he was gonna call their head office or something I waited another 15 then he decided not to come back sent a Lady by the name of Salome I never got my apologies from the guy I was made to feel like I had done something wrong I was on lunch as I work in the same center as them this was bad customer service I felt like I have ****** the item
