Dion Wired - K****tso

I purchased a Sony PS4 using my debit card which was a temporary card. I returned to the store yesterday 02.01.2018 requesting a refund. The goods were checked and okayed by staff and I was told a 10% charge would be deducted for packaging which I agreed to. However they were unable to use the cheque card number I paid with as the temporary card expired. After waiting for more than half hour for the Sales manager to arrive I told the Sales Manager K****tso about the expired card and willingly offered to produce my new platinum cheque card. The imbecile insisted he can only do it on the expired number. At first when I tried to locate my new card I couldn't see it in my bag as it was wrapped in a white paper. I called the wife at home she told me to check my bag again and I subsequently located it. When I gave the card to K****tso he tells me " you keep changing your story" meaning that I am trying to de*****. At the end what was given to me was cash which I told K****tso to rather do a cheque transfer but he refused. I want to know how Massmart employ people that blatantly tell a customer " YOU KEEP CHANGING YOUR STORY". The sales manager is a ******, *********** and rude individual. My wife worked for Massmart as a Manager for over 20 years and she couldn't believe that a Manager could speak to someone in that way. I will be forwarding this to the Massmart Ceo and the Massmart USA as well. They need to explain how this man was hired and promoted to Sales Manager.
