Horrible, bad and disgusting service

Exact in Johannesburg Kerk Street(Woolworths building) Ive never experienced such horrible, disrespectful and poor service. I went for an exchange of sizes but unfortunately didn't get them so I asked for a refund the cashier said to return after 11 o'clock as she it was still early and she's doesn't have enough funds to assist me. I went back after 2 o'clock and while I was in the queue the same cashier asked me if I was there for a laybye and I politely said no for a refund, when it was my turn she looked at the receipt and said she doesn't have money I then asked why didn't she tell me then instead of making me wait for nothing and told her that she said I must return during the day in the morning then she just chased me to go to the nearest Exact.

I went to Pritchard street in Johannesburg and the cashier that side she tried to help me and even showed me that she doesn't have sufficient funds to assist and offered me a chair to sit while she's trying to cover the funds, From the that's when I realized that I was treat unfairly at Kerk Street and decided to return back to that store I then asked the same cashier to call out her manager and she did but the 'so called' manager didn't even come to me instead discussing with the cashier and then called me he didn't even greet me nor try to understand how can he assist me SO DISAPPOINTING!!!i explained the whole situation and treatment he didn't even apologize and I could hear the cashier back chatting about me and that there's nothing she can do while the store was packed with customers and somehow trying to embarrass me. I told the manager the customer service send me back to the store for assistance and then he called another cashier to come assist and she came with bad attitude as well as she even had the nerve to tell me that they can't refund the whole thing as their not allowed to do so and per manager and second in charge pointing at the same cashier and asked me what must she do because she has to listen to them and I politely said your customer service said you should assist me and the so-called manager again kept quiet. Then the cashier gave me my money but after making sure that they disrespected me and humiliation.
