Bad horrible service

So, I went to Mr Price to exchange my pair of jeans, off which I ended up not doing so cause I was so put off by the bad service I got from the minute I walked in from the security. Her name is Sibongile, she works for Venture Security. When I walked in, I greeted and informed her that I’m here to do an exchange. She asked me where’s my receipt and I told her they emailed it to me but I still have the price tag on my jeans. She then asked me, the other small one that they give if they’ve emailed the receipt to you. I told her, I had lost that one cause they’ve emailed me the original one. Instead of informing what’s the next step, she grabs my plastic from my hand and she just pastes a small paper on my wrist. I had no idea where that is and she still doesn’t explain what I need to do or what is it for. I then ask her, is this the service you give people?! She says you gave me attitude first, so yeah. I was shocked by her response cause I never gave her attitude. I then proceed (she still hasn’t explained what I need to do and what is that small paper she pasted on wrist is for). I go to the till, speak to some lady (didn’t get her name) I ask her if can I please see the manager. She replies by saying “his on lunch” but go there by that door and ask to whoever to call “Mongameli” for you. I was shocked by how I’m sent to go look for manager, cool as I proceed I get there and ask for Mongameli and I believed his the manager (apparently his not, the manger is Sandra but I was told to look for Mongameli). Anyways, I ask him for the details of the security lady and he gives me without asking what’s the matter and I also ask for the Mr Price head office number and he once again gives me without asking what’s the matter. I left the store without exchanging. I am so disgusted by the service I got from the Security and the staff and the so called Manager. I’m tired of not reporting bad black on black service cause I don’t want people to lose their jobs. It’s firings Mr Price and Venture Security please train your staff often and teach them about customer service.
