I am not a happy client

I was so disappointed with the service i received from game store in galleria mall. I bought a iron and when my mother in law tried to use it water was leaking then I tried to return it they told me they can not help me because I had no slip then I asked for the manager the ladies at customer service started talking amongst themselves. They said it was a looted item Nosipho and jabu where very rude from the start. Nosipho (180620) called the manager, I heard her say relax it's a black person. I felt offended by that statement then I asked her why did you say that she told me "no the manager wanted to know if he needs to speak english of isizulu I got more offended. Then when the manager (Abongilele 31576) came he said to me that they can't help me without a slip then showed me a sign that said 'due to the resent unrest they cannot exchange goods without proof of payment....' after that he told me he is paging for the guy that works with irons. I waited 30 minutes he never pitched up. I got more upset then I left. I came back with my mother in law to assist me with the matter. Nosipho and jabu told lies about me they said I swore them but it's the other way around Nosipho said fuseg and ***of to me. I told her I'm a customer here she said she does not care because I don't feed her. Jabu said game store doesn't sell the I have I then went inside the store to fetch one. When I came back they called a security. They told the security that I am Givin them trouble he should chase me out the store. I then asked for the store manager. He told me the same thing that was previously said to me but he made a call then he made an exchange for me. Overall I was not happy with the way they handled the situation I wouldn't recommend the store to anyone. The employees have no manners
