Terrible customer service from Nortgate Mall & Cradlestone mall.

How difficult is it to get a R300 refund? I bought a dress in Limpopo on the 10th of November. My sister said she did not want the dress and would rather have her money back as she had bought an alternative outfit. I was back in Joburg and on the 14th I went to Northgate Mall to try and get the refund. The two ladies at the till points said they did not have cash and this was after 11am. They proceeded to do whatever they were busy with and I waked away. I then went back to work and later that same day went to Cradlestone Mall, this was around 17H40 and they said they also did not have cash. The lady at the till looked at my slip and said "Yoh it's cash. We don't have cash". She just gave me a dead stare and I took my slip from her and the dress and proceeded to Clearwater Mall. Oh how I wish I had gone there from the start. From the security lady at the front door, she served me with a smile and apologised after I told her my ordeal. I was assisted by a lovely lady by the name of Gcobisa at the till point. Her and her colleagues empathised with me and apologised for the inconvenience after I shared the run around I had to endure for a mere R300. I had gone into the store already angry and ready to throw a fit. Oh what a lovely bunch of ladies. I would like to thank Gcobisa for serving me with a smile from start to finish. Her bubbly personality and warm smile eased all my frustrations. As someone who is in the retail space, I was pleased to see a true Service Champion! Thank you Gcobisa and the Clearwater team
