horrible customer service at JET Southgate

on Sunday 11 October i went to jet Southgate to do an exchange, unfortunately I couldn't find my proof of purchase. I bought a shoe for R360 in July and by end of September the shoe was badly damaged. their return policy states that you can return a defect within 6 months. I got to the store and the cashier told me she cant assist me due to the fact that there's changes and the company is now under new ownership(TFG group). i requested to speak to the manager and she was extremely rude and told me she was doing me a favor. I felt very humiliated and sad, I left the store and came back after 10 minutes. i asked to speak to the admin manager again, upon my return I had found out that they can use online opticle to retrieve my slip. this time around the manager was very angry, called me a "know it all". she further instructed one of the cashiers to open the system for me and let me do it myself. the entire store was now looking at me and i cant even explain how embarrassed and humiliated i felt. they left me at the desk to help myself and eventually I left. I have received terrible customer service from the same store several times and never complained however this time around i decided Im never going to shop at Jet no more. I sincerely wish the TFG the best of luck and hopefully they implement the TQM system efficiently and teach their staff customer service. one of the reasons why EDCON ran out of business is because of the terrible customer service and ***********'s staff members.
