UTTERLY DISGUSTING SERVICE FROM A SUPERVISOR!!

I am utterly disgusted with the service I got from THE FIX Prominade in the Western Cape. I moved to WC from Gauteng, I purchased clothes on my mothers account and only needed to do a size exchange with no extra credit on the side as I start a new job on Monday and urgently needed small sizes to the ones that I took. Upon arrival at the store I looked for alternative sizes, When I got to the till with the clothes the teller processed a normal goods return and requested a card (which I was not in possession of as previously explained) I presented the slip and items to the teller who did not bother asking if I was transacting on account or cash. I requested to either speak to a store manager or supervisor where I was then approached by a “supervisor” who spoke to me very rudely with absolutely no interest in hearing about my query or even assisting me with fixing whatever issue I had. I was yelled at and given the most disgusting attitude I’d ever received from a supervisor, if she wasn’t at work I’m assuming she would’ve already asked me to “step outside and sort it out/literally give me a hiding”. Instead of fixing my query and advising me she got frustrated with me. I proceeded to call my mother who also wanted to get an explanation of the normal returns process and get a feasible solution from the supervisor, she rudely grabbed my phone and gave it to one of the customer assistants who calmly explained that my mom needed to buy me a virtual gift card so I could be able to make a purchase- this being explained after this supervisor lady suggested that I return to The Glen store in Joburg to get this sorted out. What an arrogant supervisor. Disgusting doesn’t even begin to describe the kind of experience I had. My mother will be closing her account as all items have been returned to the store. Maybe look into training your staff on emotional intelligence especially when they are not being attacked and someone just really needs a solution to a rather urgent solution. One thing you should probably do? Look into the work of your supervisors and interactions with clients. I AN NEVER SHOPPING AT ANY THE FIX STORE IN MY LIFE!
