Call Centre Agents need Training

I recently learnt I owe BestMed money having left the medical Aid in 2017, then I learnt email addresses are not updated if you inform them as you are leaving the medical aid and they do not factor that you may move as they only email and post outstanding claims. But no calls.

When I called today to clarify what I was owing and how I never got communication and not a single call, this process was explained. Which I feel needs an updated.

The one agent went off shouting, while my tone was calm, had to have a conversation about her tone and if she is not comfortable speaking to me to give my call to someone who is. When transfered to Finance her response to one of my questions was 'hhmm'. Now I am not sure what establishment allows people to respond with an 'hmm' but I for one find it extremely rude. I am not sure if they need to be spoken to are get further training but this is not acceptable. This is not how you treat customers especially ones that were planning to return but now would rather not and tell the over 6 people I refereed there to leave it.
