Rude FNB banker

Today I made an enquiry through the my secure chat feature of the FNB application. I had lodged a dispute against a certain service provider and in the process my card was canceled. All I wanted to know was if it was possible for me to reverse the cancelation and to get further clarification of why my card was canceled. I was assisted by the very rude and unhelpful banker Esethu Ngqeleni. I am so disappointed by service,
