debit card dispute

Good day, I'm very disappointed with the service I have been receiving from FNB, last year December I logged two debit card dispute, only one was resolved last month after I made a follow up with them. I have been calling regarding the second dispute and every consultant promised to call me back with feedback and then nothing, I spoke to Charity on the 19-01-2022, Mathabo 31-01-2022, Sibongile 14-02-2022, Bafana 17-02-2022 and Sibongile Mabule today, she also promised that her supervisor or manager by the name of Kabelo Molefe will give me a call back regarding the dispute and is now 17:00 and haven't received any call from him, I'm just not happy with how they treat their customers!
