Unhappy with the service I got from an unprofessional,********* and unempathetic customer service agent

I am so deeply hurt and dissatisfied and disappointed by an agent at Cash Converters Eyethu Shopping Center who kept on humiliating my husband by telling him that I am bossy and talkative and that he thinks I make dominate him at home just because I was just asking relevant questions regarding my loan contract against my smartphone.I had to know more about loan terms and conditions because today was my due date to repay my debt.I also wanted to pay R800 which was half the price of my loan debt.And so I tried to enquire from him if I could pay R800 and come back 2 days later to come and pay the balance amount of R833 in 2 days tome20/07/2024)which he refused to have empathy or go an extra mile.He however took only R370 from me for interest fee instead of the R350 which was printed on my loan contract.He then said I was too talkative and he was the only bull in the kraal and he is in charge when I wanted to follow the procedure he was conducting.He afterwards tore in pieces my loan document which I was given on the 18/07/2024 and printed a new one that said I have to come back before 18/08/2024 to repay my loan debt.Subsequently what perplexed me was that he never issued me with a reciept that showed that I paid R370 interest fee today 18/07/2024.I have never seen what this customer service agent did in my life.I am so angry,disappointed and feel so sorry for my husband.
