Rude customer service agent - Ntombi

I called their accounts department to change my payment method and spoke to Ntombi who was extremely rude and disinterested in my request. I asked her to put me through to her line manager and she put me on hold for about 15minutes. I eventually spoke to Thabang the team leader who assisted and he even called back to confirm that my request was processed successfully. Do away with Ntombi, she is bad for your business.
