Lunga, Agent from Capitac bank customer services Ugly service

Lunga is the worst customer service Agent I have ever came across I don't know if it was too early for him to take the call but it was 07:55 when I made the call. I don't know maybe he was still sleeping. I told him my query and he requested a security check after I had a challenge with my phone to confirm the remote message and I told him bare with me my phone is giving me a problem, but the way he was in the rush he moved to a security check and asked me my name as it appear on my card I couldn't hear him so I gave him my full name and he moved to my contact number and he says it's incorrect I have failed the security check I told him why don't u move to the next question because the number was correct he denied my contact number says it's incorrect but I bank with that number how can I get it wrong he could have moved to next question but he decides to tell me to call again in 24 hours I then asked him to help navigate on the app coz I have it opened and I have done it before just that I don't remember how it was done. He says he won't help me I should call tomorrow. The worst service I have ever came across he was in a rush to do something maybe or he work up on the wrong side of the bed. He blantly refused to tell me how to dispute a debit order on the app.
