Poor Service with Bad Attaitude attached

Sunday afternoon, at 16:30 I walked into Hi-Fi Corp Menlyn after receiving horrible service from New World. i wanted to buy a surround sound. Eventually 10 minutes later a young man Thsepo came to assist me after being ignored by other employees. He was helping me decide between the LG and Pioneer. At 16:47 other employees started shouting that the tills are cashed up and I saw that the doors were locked after hearing the sound on that we were testing. While waiting for another 10 minutes to pay at the cashier while Tshepo was getting my item, there was nobody to help us. At 17:01 a lady rushed into the store forgetting something. We were greeted with arrogant attitude. I was continuously reminded that they cashed up. When I told Tshepo to leave my stuff the lady quickly made a plan to get me a receipt. I got told to come back another day as they couldn't give me an extended warranty. I work 7 days a week and do not appreciate being treated like a worthless person after I spent R6000 in your store! I AM A FIRST TIME BUYER AND DEFINITELY WON'T COME BACK. I will also tell everybody I know to BOYCOTT your store after I spent R500 more than New World and get treated like I did!
