Poor service received from Jet Chatsworth and the Customer Services Call Centre

My card was cloned at the Jet store in Galleria on the 26 March 2023 and used in the Usave store in Umlazi for an amount of R9500 ( Don't even ask how it was used at a supermarket, it still boggles me too). I logged a dispute and after 1 month and a half of running after the ***** department, I finally got feedback. Two weeks ago I visited the Jet store in Chatsworth to get a new card as the old one could no longer be used due to the *****ulent transactions. This was another nightmare as nobody there knew what to do. I asked for the manager and I was told to go find him in the office by the shoe section. When I get there, the door is closed - I ask staff to please call him. When they go in, he tells them to tell me that he is not available ( I hear this whilst standing outside the door).. I then leave as I needed to get back to work. Long story short, I go back the next day, Finally found a staff member that knew what was happening, issued me a new card, called the call centre, linked me up and everything was sorted...or so I thought. I visit Edgars today to make a purchase, get to the till, card declines. I go back to Jet, spoke to Phindile, says they offline and she cant check anything. Called the call centre, get told that my NEW card is from a faulty batch and the CVV is the problem, I need to get a replacement card. I get issued with a new card, purchase a packet of sweets before leaving, just to make sure my card is working. I get back to Edgars, use my card and believe it or not, it declines! At this point my frustration level was hitting the roof. I then call customer services again, the agent tells me that my card is expired, I told her that I just bought sweets in the store with the same card and it was fine.. she still says its expired and I must go back to the store. I ask for a manager or someone that can give me proper answers, she then connects me to Bongi who apologized but still could not help me. She said I must go to the store and get a replacement card I must make sure the CVV number is not one that will expire soon...how does one even do that , and is it the customers responsibility to do this ? I asked her to log a complaint and give me a reference number, she says she cannot provide a reference number. I eventually cut the call with no joy. I am considering closing my account.
