FNB's terrible customer care

I cannot believe the disgusting service I just received from FNB customer care. The agent started off with the call sounding super annoyed even before I told him my problem. while explaining my problem, he sounded very irritated as if it's not his job to help FNB clients. As I am clarifying why I need assistance, he makes a remark on the call most probably thinking that his on mute.

I am super annoyed and disappointed at how I was being addressed on the call and I believe this is not the way you should treat your clients.

If FNB is interested in the agent's name, I am more than willing to provide it.
